I would like to remove commas , at the end of each line in my file.
sed only remove the last comma character, but I would like to remove all the commas (and maybe all other character, like::

at the end of a lines.
My command: sed 's/,$//' file

for example my file contains:
Solaris,
Debian,,,,,
Kubuntu,,
Unix,,,,,,,,
Apache:::

Thanks in advance.

Pretty straightforward.

Code:

sed 's/,*$//' file                 # remove all trailing commas
sed 's/[,:]*$//' file              # remove all trailing commas and colons
sed 's/[^[:alnum:]]*$//' file      # remove all trailing non-alphanumeric characters

Old style sed regex using () instead of [], removing all trailing commas and colons:

Code:

sed 's/\(,\|:\)*$//' input
