Hello,

Code:

history | tail -5

for the logged in user. Otherwise as root

Code:

tail -5 /home/username/.sh_history

(AIX Unix)

Kind regards,

Eric

Hi,

If you're not sure, then why not test it? You'll know at an instance if it works or not.

Kind regards,

Eric

This gives you the 10 most used commands.

Code:

history | awk '{print $2}' | awk 'BEGIN {FS="|"}{print $1}' | sort | uniq -c | sort -n | tail | sort -nr
