Run text file as commands in Bash
LinuxBashUbuntuTerminalCommandLinux Problem Overview
If I have a text file with a separate command on each line how would I make terminal run each line as a command? I just don't want to have to copy and paste 1 line at a time. It doesn't HAVE to be a text file... It can be any kind of file that will work.
example.txt
:
sudo command 1
sudo command 2
sudo command 3
Linux Solutions
Solution 1 - Linux
you can make a shell script with those commands, and then chmod +x <scriptname.sh>
, and then just run it by
./scriptname.sh
Its very simple to write a bash script
Mockup sh file:
#!/bin/sh
sudo command1
sudo command2
.
.
.
sudo commandn
Solution 2 - Linux
you can also just run it with a shell, for example:
bash example.txt
sh example.txt
Solution 3 - Linux
Execute
. example.txt
That does exactly what you ask for, without setting an executable flag on the file or running an extra bash instance.
For a detailed explanation see e.g. https://unix.stackexchange.com/questions/43882/what-is-the-difference-between-sourcing-or-source-and-executing-a-file-i
Solution 4 - Linux
You can use something like this:
for i in `cat foo.txt`
do
sudo $i
done
Though if the commands have arguments (i.e. there is whitespace in the lines) you may have to monkey around with that a bit to protect the whitepace so that the whole string is seen by sudo
as a command. But it gives you an idea on how to start.
Solution 5 - Linux
cat /path/* | bash
OR
cat commands.txt | bash
