well you may need that bash after all hehe... expanding * metachar

try your /bin/bash -c with double quotes

Mistake on my part, when i did your first modification, i didn't incldue the *, duh.

So I fixed that, included your catch lines.

And the error is now:

Code:

 [20:33] Tcl error [lookup_string]: grep: /home/eggdrop/eggdrop/logs/sdcara.log*: No such file or directory

It seems to take the wildcard literally...

grep(1) returns 1 if no matches were found, and any return code but 0 means "abnormal program termination"

so you need to catch the error and continue:

Code:

if ![catch {exec /bin/grep -i $args /path/$chan.log*}] {  # match(es) found, do your stuff } else {  # no matches}

Thank you!
Ok, some progress. Now I get this error

Code:

 [19:51] Tcl error [lookup_string]: child process exited abnormally

Ideas?

no need to fork bash; also get rid of those single quotes:

Code:

exec /bin/grep -i $args /path/$chan.log*

I'm trying to create a script that will let me lookup text in log files. I figured using grep externally would provide me with alot of flexability. I got it working, but it only works using one file, and I'm having my log files divided out by day, so I want to use the wildcard * liek I do on a shell to have grep lookinto all of them. Here's the code for the wildcard version:

Code:

bind pub - {??} lookup_stringproc lookup_string {nick host handle chan args} {        putquick "NOTICE $nick :Looking up: $args"        set chanmod [string trimleft $chan #]             set out [exec /bin/bash -c 'grep -i $args /home/eggdrop/eggdrop/logs/[string tolower $chanmod].log*']        set arr [split $out \n]        foreach line $arr {                putquick "NOTICE $nick :$line"        }}putlog "FlashBack loaded."

The error I get when DCCed into eggdrop is:

Code:

 [19:35] Tcl error [lookup_string]: -i: -c: line 1: unexpected EOF while looking for matching `'' -i: -c: line 2: syntax error: unexpected end of file

The command : /bin/bash -c 'grep -i $args /home/eggdrop/eggdrop/logs/[string tolower $chanmod].log*' works in the shell tho if im logged in. (after fixing up the varible parts of course)

Anyone have any ideas to make this work? Or... If i cant do that i could have 1 log file, which I know how to, but is there a way to change the timestamps to include the ddMMMyy date along with the time? I didnt see an option for that in the conf.
