Shell Can't edit crontab

[blind0ne]

Hello, I wan't to edit my crontrab in order to add one simple script, but I'm really unfamilir with vi or vim and already forgot how to exit from it few times (can't rememer how many), so using crontab -e is not the way for me, so I've tried to change my EDITOR variable to nano from my current fish shell but I faced something unpredictable and tried to do this from BASH then but also crushed. Please help me with the link to appropriate docs or explain why and what should I do just to have comfort with crontab.

root@OffGateway /u/l/monitor# set -gx EDITOR fish

fish(1) is not an editor, it's a shell. You need to set the EDITOR variable to an editor, not a shell. So that's nano(1) if I read it correctly; set -gx EDITOR nano

root@OffGateway /u/l/monitor [1]# bash 
[root@OffGateway /usr/local/monitor]# set EDITOR=nano

Bourne shells (like bash) use export in order to export the variable to subshells; export EDITOR=nano.
