Data extraction in perl variable
HI,

i have variable in perl like below

HTML Code:
$tmp="/home/sai/automation/work/TFP_GN.txt"
 
it can conatain any path its filled from config file.
 
now i want extarct the path upto this /home/sai/automation/work/    and put it in another variable
 
say $newtmp=="/home/sai/automation/work/"
i mean last any file name like TFP_GN.txt or dummy.csc etc should be removed and want only directory path like /home/sai/automation/work/

Any thought ?

Thanks,
Raghav

You could do it with a regex
Code:
($path,$file)=$tmp=~/(\/[^\/]+\/)+([^\/]+)/;

or use a module which will catch cases you haven't thought of
Code:
use File::Basename;
$newtmp= dirname($tmp);

Use the regex below.

Code:
echo "/home/sai/automation/work/TFP_GN.txt" | perl -pe 's/\w+\.txt//g'
/home/sai/automation/work/
