hi,

I have a file that contains one line with , at the end of it and I want to remove it using sed

I tried

s/,$//g

Code:

> cat file2
abc 1234 def
lmn 4567 xyz,
qrs 5689 mou
> sed "s/,$//g" <file2
abc 1234 def
lmn 4567 xyz
qrs 5689 mou
>

$ anchors to end of a line
^ anchors beginning of a line

Code:

> sed "s/,$//g" <file2

I think -g is not needed here

The 'g' in the command is extra as there can only be one instance per line. Command should simply be:

Code:

>sed "s/,$//" <file2

cat file2 | awk -F, '{ print }'
