Remove the first comma in a TXT fil
 
I would like to remove the first comma in a text file. My file is comma delimited data so i want to be sure that i only strip the first comma and no other ones. Can you please help me?

To remove the first comma in every line within the file (and not simply the first comma in the file as a whole):

Code:
sed -i.backup 's@,@@' filename
This will modify the file directly, but store an unmodified, backup copy of the file as filename.backup.

Thank you for your help, but I was not clear. I would like to be able to remove ONLY the first comma in the file.

If the first comma is on line 1:
Code:
sed -i.backup '1 s@,@@' filename
If the first comma is on another line, change the number as appropriate.
