Bash script

[gavos]

Hello guys,
Im creatin a bash script for making crontab jobs with ease for a user who dont have a clue.. I dont want the comments o be displayed so i want something like : if the first character of line is"#" then.. etc.. Of course i can print this result with sed and grep but i want to know in my script whats happening so i can do something else if tha "#" character appears... Any ideas how can i implement this??

Eh, the script wont print comments if preceded by #
Or do I misunderstand your question?

I know ways so that the comments wont be displayed, but thats not what i want.. I want to know in my script if the line that i am processing is a comment line or another line.. Is there a way to know this?

Ok i solved my problem.. It was so easy though im a newbie shell programmer.. Ok now my problm is that i cant append a single line in the end of the crontab file.. Something like
crontab -l | sed '$a\Text to be appended' | crontab - gives me an error on my mac.. Has anyone any ideas of how this simple work could managed out..

What's the error message? I'm not an amazing sed guy, but the crontab stuff looks right.
