Easy question for you pros
I have a folder with about 4000+ files. I would like to compress all these files with one command. When I type "compress *.ext" for example, I get "arg list too long". I tried the following:

for k in *
do
compress *.ext
done

Still got "The parameter list is too long." How can I compress all these files with a single command?

Thanks in advance.

I did a search on the word compress and found the following that might help:

Try searching to see if you find anything else. Good Luck.

I got it to work. Thanks.

I did this...

for in k *.ext
do
compress $k
done

This compressed all the files I needed with the extension I specified.

find ./ -name '*.ext' -exec compress {} ';'


I dont know what compress does but this is the way to handle large number of files...for example if you want to find the size of each file in a directory

use find ./ -name '*.jpg' -exec du -sk {} ';'

Another option is to use awk

ls -1 | awk '{print "du -sh " $1}' | sh

hope it helps

Two ways to achieve this (and similar) requirements:

1. use "find" with the "-exec" clause. This has already been mentioned and is the "modern" way to do this

2. use "xargs". This is the "classical" way to handle large parameter lists and is not any longer recommended anyways..
