Clear all lines in a csf deny file that contains text: Added by Fail2Ban

bmxakias · 08-25-2017, 08:15 AM

None work

This one just display the contents of the file:

Quote:

sed '/Added by Fail2Ban/d' /etc/csf/csf.deny

And this one:

Quote:

sed -i 's/Added by Fail2Ban/d' /etc/csf/csf.deny

report an error:

Quote:

sed: -e expression #1, char 21: unterminated `s' command

Any ideas?

Thank you

Code:

sed '/pattern to match/d' input-file

is correct.

Since you have spaces in your pattern you should delimit those spaces with the backslash.

Code:

sed '/not delimited pattern/d'  input-file // probably will not work
sed '/yes\ delimited\ pattern/d' input-file // probably will work
