launch a command only if
Hi!
I would launch this command:

tar -cvvf logswitch.tar `find *.log* -mtime +5` --remove-files

only if

find *.log* -mtime +5

find some files.

Thanks in advance.

Code:
FILES=$(find *.log* -mtime +5)
if [[ "$FILES"  != "" ]]; then tar -cvvf logswitch.tar $FILES --remove-files; else echo NO FILES FOUND; fi

running command on condition
I assume you don't want the file to be created if no files are given.
$(FILES)=$(find .....)
[[ -z $FILES ]] || tar ... $(FILES)

mmmm... Good one.
The syntax is not correct though, at least for ksh/bash... It should read:
Code:
FILES=$(find .....)
[[ -z "$FILES" ]] || tar ... $FILES
Regards.
