I would like to replace the following sentence "lw 2,\" with the sentence "lw 2" however I cannot do it with

sed -i 's|lw 2,\|lw 2|g' "filname"

I get the following error

sed: -e expression #1, char 15: unterminated `s' command

It seems that it doesn't like the "\"


You just need to escape the backslash:

's|lw 2,\\|lw 2|g'
  • 2
    ... because the single backslash would otherwise escape the | used (for whatever reason) as a delimiter.
