Thanks a lot for all these examples. Very useful to learn shell scripts for a newbie like me :)
Hi
there is a problem with your script
when you execute it , if there is any file or directory which it’s name contains ” ” ( i mean space ) , you would get some error.
to deal this error you should modify all your if clause to :
if [ -f “$f” ]
another note is that , we expect a “ls” comand to accept an argument as a path , for example : ls /etc/ —> should list all the files and directories in /etc/.
to deal this i suggest you to modify these lines :
output=””
cd “$1” ##this line is added between the 2 lines you had##
for f in *
.
.
.
echo “Total size of regular files : $totsize”
cd “-” > /dev/null ## and this line is added at the end of script##

thnx for your nice ideas in scripting
