Find files of specified size using bash in Unix
BashUnixBash Problem Overview
I am looking for a Unix command to print the files with its size. I used this but it didn't work.
find . -size +10000k -print.
I want to print the size of the file along with the filename/directory.
Bash Solutions
Solution 1 - Bash
find . -size +10000k -exec ls -sd {} +
If your version of find won't accept the + notation (which acts rather like xargs does), then you might use (GNU find and xargs, so find probably supports + anyway):
find . -size +10000k -print0 | xargs -0 ls -sd
or you might replace the + with \; (and live with the relative inefficiency of this), or you might live with problems caused by spaces in names and use the portable:
find . -size +10000k -print | xargs ls -sd
The -d on the ls commands ensures that if a directory is ever found (unlikely, but...), then the directory information will be printed, not the files in the directory. And, if you're looking for files more than 1 MB (as a now-deleted comment suggested), you need to adjust the +10000k to 1000k or maybe +1024k, or +2048 (for 512-byte blocks, the default unit for -size). This will list the size and then the file name. You could avoid the need for -d by adding -type f to the find command, of course.
Solution 2 - Bash
Find can be used to print out the file-size in bytes with %s as a printf. %h/%f prints the directory prefix and filename respectively. \n forces a newline.
Example
find . -size +10000k -printf "%h/%f,%s\n"
Output
./DOTT/extract/DOTT/TENTACLE.001,11358470
./DOTT/Day Of The Tentacle.nrg,297308316
./DOTT/foo.iso,297001116
Solution 3 - Bash
Assuming you have GNU find:
find . -size +10000k -printf '%s %f\n'
If you want a constant width for the size field, you can do something like:
find . -size +10000k -printf '%10s %f\n'
Note that -size +1000k selects files of at least 10,240,000 bytes (k is 1024, not 1000). You said in a comment that you want files bigger than 1M; if that's 1024*1024 bytes, then this:
find . -size +1M ...
will do the trick -- except that it will also print the size and name of files that are exactly 1024*1024 bytes. If that matters, you could use:
find . -size +1048575c ...
You need to decide just what criterion you want.
