To count underscore in filename
Hi All

I have a filename like below
Code:
adsf_ghjt_kop_pol.csv

Can you please get me a command for counting the number of underscore in the filename.

In the above filename I should get output as 3, since the file name is having three underscore

Hello ginrkf,

Could you please try following and let me know if this helps you.
Code:

OR
echo FILENAME |  awk '{A=gsub(/_/,X,$0)}END {print A}'

Thanks,
R. Singh

bash / ksh93 / zsh, all in shell without subshells:
Code:
fname=adsf_ghjt_kop_pol.csv
uscores=${fname//[!_]}
echo ${#uscores}
