$(variable#pattern)

Hanry Zhou — Mon, 25 Aug 2003 21:17:59 GMT

"If the pattern matches the begining of the variable's value, delete the shortest part that matches and return the rest".

For the instance of ${path#/*/}, and
path=/home/billr/mem/long.file.name

I know the result would be billr/mem/long.file.name, but why, can you explain to be why in detail?

Thanks,

Hi Hanry:

Here, the "shortest part that matches" is the slash character ("/") followed by any character ("*") and then followed by another slash character. Hence, if you remove "/home/" you have met this criteria, yielding "/billr/mem/long.file.name".

Using "${path#/home/}" would have the same effect here.

This message has an interesting topic or subject line that might be causing the forums profile page issues. I am doing a reply to test my profile page. If it does not appear, that would explain why James R. Ferguson's profile page is not work. I am sorry for any inconvenience this might cause anyone.

Interesting theory, Paul. It appears you're right, because now both profiles get 404'd. Be sure to report this to Dan's issues thread, would you please?

Hi Paul:

Very interesting observation! I noticed this morning that I could not get to my profile, yet could not find any others with problems (e.g. any "J" user as has happened on other occasions). Your profile is now inaccessible too, so I suspect that you have found the reason. I have an open call with Dan and will foward this information to him with my thanks to you!

p.s. -> Pete Randall's profile cannot be accessed anymore, too, for having posted here :-))

Regards!

Hi Paul, Pete & Dan:

Thanks to Dan G. the profile access to me, Paul and Pete has been repaired. Paul, you were correct, the special characters in this thread's subject were responsible. Nice catch!

Dan, its always great to have you around.

Regards!
