How to search a pattern and remove the line using sed which contains special characters like "ranasnfs2:/SA_kits/prod"

I tried using a variable to hold the complete string and then recall the variable in sed command but it is not working.

echo $a
ranasnfs2:/SA_kits/prod
    sed -i '/"$a"/d' test.txt
    cat test.txt | grep -i SA
/SA_kits        -rw,suid,soft,retry=4   ranasnfs2:/SA_kits/prod

  • Which sed are you using? GNU? Can you identify a character which is guaranteed not to occur in the string to search for? E.g. "%". – Yunnosch Jun 21 '17 at 19:33

  • Switch from `s///` to `s|||`, e.g. – Cyrus Jun 21 '17 at 20:18

You need to escape the slash character. Use this for deleting lines which contain a /:

sed '/\//d' file
