line_removal.pl (known_hosts)
Posted by on May 16, 2008
Manually removing entries from your known_hosts doesn’t take my of an effort. Still, it’s something you can grow tired of. Especially so after resent events (DSA-1571). That is why I’ve now written my very own line_removal.pl script.
Basically you feed the script one or more line numbers. Corresponding lines in your ~/.ssh/known_hosts will then be deleted.
andreas@leto:~$ ./line_removal.pl 22
Removing line #22 from /home/andreas/.ssh/known_hostsandreas@leto:~$ ./line_removal.pl 3 37 29
Removing line #37 from /home/andreas/.ssh/known_hosts
Removing line #29 from /home/andreas/.ssh/known_hosts
Removing line #3 from /home/andreas/.ssh/known_hosts
To be honest I really don’t know if I’ll ever use this script against more than one line at a time. Somehow it still seemed wrong not to support the option of feeding it multiple arguments.
