SED question: newbie here.

Hello... I wanted to figure out how to remove the 1st instance of a comma from a file..

100+ line file
-------------
'test1'
,'dudes are cool' <-- remove comma from first instance of comma in file
,'cool dude'
,'bbbbbb'

I tried everything from
cat jigar|tr , >1.txt to cat jigar|sed 's/,/1'

Thanks!

With awk:

awk -F, 'NR==1{print $2}1' file

Regards

sed:

sed 's/^,//1' inputfile
