I don&#39;t think you can, but you can prefix it with an `!` to treat the command as a new shell command

    [alias]
        pushcur = ! git branch | grep &#39;*&#39; …



I typically make small `git-` scripts and put them in a directory that&#39;s in my path (`~/.local/bin`). Check out [git-extras](https://github.com/visionmedia/git-extras) for a bunch of good examples.

A simple workaround is to add it as **shell alias**. 

Here is an example:
  
```shell
alias grf=&quot;git rebase -i $(git merge-base --fork-point master)&quot;
```  

(rebase on the fork commit of current branch and master interactively)

For bash, add it to `~/.bashrc`, then you can simply use `grf`.



Searching in the web about async functions, I found many articles using setTimeout to do this work:

    window.setTimeout(function() {
       console.log(&quot;second&quot;);
    }, 0);
    console.log(&quot;first&quot;);

Output:

    first
    second

This works, but is a best practice?

Is setTimeout a good solution to do async functions with javascript?

Can I get a list of all registered directives, services, controllers, etc. *at runtime* . . . ?

I work on feature branches that have annoying big names, so I often end up grepping my current branch name when I need to push up to the feature branch from my local feature branch, like so: 

    git branch | grep &#39;*&#39; | sed &#39;s/* //&#39; | xargs git push origin

This works fine. I want to make this an alias, so I did this in `~/.gitconfig`: 

    [alias]
       pushcur = branch | grep &#39;*&#39; | sed &#39;s/* //&#39; | xargs git push origin

Now, when I run `git pushcur`, I get the following error: 

    usage: git branch [options] [-r | -a] [--merged | --no-merged]

Leading me to believe that the alias is not properly parsing the pipes. Is there something else I should do to achieve the desired alias?

I want to delete all the tags from a Git repository. How can I do that?

Using `git tag -d tagname` delete the tag `tagname` locally, and using `git push --tags` I update the tags on the git provider.

I tried:

    git tag -d *

But I see that `*` means the files from the current directory.

    $ git tag -d *
    error: tag &#39;file1&#39; not found.
    error: tag &#39;file2&#39; not found.
    ...

Consider I have a lot of tags, and I want to delete them, all.

Delete all tags from a Git repository

Currently I have

1. Empty GitHub repo
2. SSH server repo (main)
3. Local Repo

SSH server repo was the most up-to-date repo (production site) so I did a Git clone from there to local. I then tried to do a `git push` to GitHub.

Everything went OK but then it said something about filename.gz being too large for GitHub. I didn&#39;t need this file so I ran several Git commands to get rid of it from Git cache then pushed back to SSH server.

I don&#39;t see the large file locally but it&#39;s still on SSH server even though `git diff` returns nothing and git push returns &quot;Everything is up-to-date&quot; - And even though the file is not visible in local repo when I try to push to GitHub I still get error about it 

&gt; remote: error: File fpss.tar.gz is 135.17 MB; this exceeds GitHub&#39;s file size limit of 100 MB

I followed steps under &quot;fixing the problem&quot; [listed on GitHub help](http://help.github.com/articles/working-with-large-files) so shouldn&#39;t that have been enough?

How is the file still in the ether when it&#39;s not local or listed in git status/diff/push?

Can&#39;t push to GitHub because of large file which I already deleted

This will be my first git use. I have added new files ( a lot ) to the folder/project ( git local repository).

I went through online tutorials and forums and see i can do 

```
git commit -a
```
So I go to the base folder of the repository and do a 
```
sudo git commit -a
```
But then, some screens comes up and asks me to add a comment which i do. i do not know how to proceed or exit. I do not want to mess up so i did ctrl + Z and did not do anything.

Can you guys please outline the commands I need to use?

    git commit -a 

and 

    git push?

How to add multiple files to Git at the same time

I have a company GitHub account and I want to back up all of the repositories within, accounting for anything new that might get created for purposes of automation. I was hoping something like this:

    git clone git@github.com:company/*.git 

or similar would work, but it doesn&#39;t seem to like the wildcard there. 

Is there a way in Git to clone and then pull everything assuming one has the appropriate permissions?

I started my git bisect by specifying good and bad revisions but I don&#39;t think they registered. Additionally, as I am attempting to specify git bisect good and bad, I don&#39;t think git is doing anything. I would like to abort the entire bisect so that I can re-initiate the operation. `git bisect reset` seems to be what I am looking for, but I want to double check before potentially messing anything up.

How to Abort Git Bisect

I have a bash script that looks like this:

    #!/bin/bash
    wget LINK1 &gt;/dev/null 2&gt;&amp;1
    wget LINK2 &gt;/dev/null 2&gt;&amp;1
    wget LINK3 &gt;/dev/null 2&gt;&amp;1
    wget LINK4 &gt;/dev/null 2&gt;&amp;1
    # ..
    # ..
    wget LINK4000 &gt;/dev/null 2&gt;&amp;1

But processing each line until the command is finished then moving to the next one is very time consuming, I want to process for instance 20 lines at once then when they&#39;re finished another 20 lines are processed.

I thought of `wget LINK1 &gt;/dev/null 2&gt;&amp;1 &amp;` to send the command to the background and carry on, but there are 4000 lines here this means I will have performance issues, not to mention being limited in how many processes I should start at the same time so this is not a good idea.

One solution that I&#39;m thinking of right now is checking whether one of the commands is still running or not, for instance after 20 lines I can add this loop:

    while [  $(ps -ef | grep KEYWORD | grep -v grep | wc -l) -gt 0 ]; do
    sleep 1
    done

Of course in this case I will need to append &amp; to the end of the line! But I&#39;m feeling this is not the right way to do it.

So how do I actually group each 20 lines together and wait for them to finish before going to the next 20 lines, this script is dynamically generated so I can do whatever math I want on it while it&#39;s being generated, but it DOES NOT have to use wget, it was just an example so any solution that is wget specific is not gonna do me any good.

Bash script processing limited number of commands in parallel

Bash allows to use: `cat &lt;(echo &quot;$FILECONTENT&quot;)`

Bash also allow to use: `while read i; do echo $i; done &lt;/etc/passwd`

to combine previous two this can be used: `echo $FILECONTENT | while read i; do echo $i; done`

The problem with last one is that it creates sub-shell and after the while loop ends variable `i` cannot be accessed any more.

My question is:

How to achieve something like this: `while read i; do echo $i; done &lt;(echo &quot;$FILECONTENT&quot;)` or in other words: How can I be sure that `i` survives while loop?

Please note that I am aware of enclosing while statement into `{}` but this does not solves the problem (imagine that you want use the while loop in function and return `i` variable)

If I have a csv file, is there a quick bash way to print out the contents of only any single column?  It is safe to assume that each row has the same number of columns, but each column&#39;s content would have different length.

How to extract one column of a csv file

I am running the following command to get the number of processors/cores in Linux:

    cat /proc/cpuinfo | grep processor | wc -l

It works but it does not look elegant. How would you suggest improve it ? 

Number of processors/cores in command line

I&#39;m studying the content of this **preinst** file that the script executes before that package is unpacked from its Debian archive (.deb) file.

The script has the following code:

    #!/bin/bash
    set -e
    # Automatically added by dh_installinit
    if [ &quot;$1&quot; = install ]; then
       if [ -d /usr/share/MyApplicationName ]; then
         echo &quot;MyApplicationName is just installed&quot;
         return 1
       fi
       rm -Rf $HOME/.config/nautilus-actions/nautilus-actions.conf
       rm -Rf $HOME/.local/share/file-manager/actions/*
    fi
    # End automatically added section

My first query is about the line:

    set -e

I think that the rest of the script is pretty simple: It checks whether the Debian/Ubuntu package manager is executing an install operation. If it is, it checks whether my application has just been installed on the system. If it has, the script prints the message **&quot;MyApplicationName is just installed&quot;** and ends (`return 1` mean that ends with an “error”, doesn’t it?).

If the user is asking the Debian/Ubuntu package system to install my package, the script also deletes two directories.

Is this right or am I missing something?

How can I make any use of PYTHONPATH? When I try to run a script in the path the file is not
found. When I cd to the directory holding the script the script runs. So what good is the
PYTHONPATH?

	:/home/randy/lib/python

	$ tree -L 1 &#39;/home/randy/lib/python&#39;

	├── gbmx_html.py
	├── gbmx.py
	├── __init__.py
	├── __pycache__
	├── scripts
	└── yesno.py

	$ python gbmx.py -h
	python: can&#39;t open file &#39;gbmx.py&#39;: [Errno 2] No such file or directory

	$ cd &#39;/home/randy/lib/python&#39;

After cd to the file directory it runs ..
