Different epoch conversion result for bash and csh users
Hi there

I'm using this script to convert command line history with Epoch time stamp to human readable. While it works fine with users with /bin/csh shell, it fails to convert for users with /bin/bash shell. Why is this happening? I even changed and added * and [0-9] after the # but it still didnt work..any idea what I'm doing wrong?

Code:
cat /var/log/user_history/root_history  | while read line ; do  if [[ $line =~ '^#' ]]; then  date -d "@$(echo $line | cut -c2-)"; else echo $line ; fi; done

This is how the original history log look like:

Code:
tail /var/log/user_history/root_history
#1348524075
exit
#1348565492
crontab -e
#1348609978
df -kh
#1348610010
exit
#1348644767
df -h

These are my failed attempts

Code:
 do  if [[ $line =~ '^#[0-9]' ]]

 do  if [[ $line =~ '^#*' ]]

Meanwhile for csh users, I am getting converted logs

Code:
# tail /var/log/user_history/Epoch_Convert/upbadm
#+1345026511
exit
#+1345093905

Could it be because the csh users' history logs have a plus sign "+" but the bash users' dont have the "+" sign?

Drop the quotes around ^#. In bash, the second operand for =~ is a pattern. Since you've quoted the pattern, it is not being treated as a pattern but as a string. Hence, only the else statement is executed.
