thanks guys! I was/am trying this too: `LINE: while ( defined( $_ = <$Rlog> )) { s/^Alert Level\s0(?:[3-9]\|\d{2,})/(?!.Log Entry)/DEREK!!!!\n$&/s +; } continue { print $Plog $_; }` [download] but keep getting this error: `Bareword found where operator expected at foo line 12, near "s/^Alert +Level\s0(?:[3-9]\|\d{2,})/(?!.Log Entry)/DEREK!!!!" Backslash found where operator expected at foo line 12, near "DEREK!!! +!\" syntax error at foo line 12, near "s/^Alert Level\s0(?:[3-9]\|\d{2,})/ +(?!.Log Entry)/DEREK!!!!!" Execution of foo aborted due to compilation errors.` [download] ORDER OF print new code where arrows are. `Log Entry 10: 06 Feb 2011 10:36:26 ---> Alert Level 2: Informational ---> Keyword: Type-02 127002 1208322 Soft Reset Logged by: Baseboard Management Controller; Sensor: System Event 0x204D4E79AA0200B0 FFFF027000120300` [download]	[reply] [d/l] [select]

You have one too many slashes in your s/// (you have 4, but you can only use 3). Either backslash one of the 2 in the middle, or choose different delimiters: `s/^Alert Level\s0(?:[3-9]\|\d{2,})/(?!.Log Entry)/DEREK!!!!\n$&/s; ^ ^ ^ ^ \| \| \| \| \| \| \| \|` [download]	[reply] [d/l]
Re^3: splice an array (alternate delimiters) by Anonymous Monk on May 04, 2011 at 13:24 UTC
I second toolics suggestion of using alternate delimiters. These are all equivalent `perl -MO=Deparse -e " s///g " perl -MO=Deparse -e " s\\\g " perl -MO=Deparse -e " s[][]g " perl -MO=Deparse -e " s()()g " perl -MO=Deparse -e " s{}{}g " perl -MO=Deparse -e " s!!!g " perl -MO=Deparse -e " s###g " perl -MO=Deparse -e " s vvvg " perl -MO=Deparse -e " s ___g " perl -MO=Deparse -e " s {}//g " perl -MO=Deparse -e " s {}\\g " perl -MO=Deparse -e " s {}vvg " perl -MO=Deparse -e " s {}()g " perl -MO=Deparse -e " s {}[]g " perl -MO=Deparse -e " s {}<>g " perl -MO=Deparse -e " s<><>g "` [download] They all output `s///g; -e syntax OK` [download] But don't get fooled by the balancing act, it doesn't work for other chars like « and » `$ perl -MO=Deparse -e " s«»«»g " Substitution replacement not terminated at -e line 1. $ perl -MO=Deparse -e " s«««g " s///g; -e syntax OK` [download] s'''g is special in that it doesn't interpolate	[reply] [d/l] [select]

I am not getting this solution guys. I appreciate the help, but had a hard time understanding Rolfs code and played with it for a while with little success. With that being said, my temp solution, I understand is the way I would like to follow. while ( defined( $_ = <$Rlog> )) { s/^Alert Level\s0*(?:[3-9]\|\d{2,})/DEREK_SMITH\n$&/s; } continue { print $_; } ###-- this works, but only half way. __OUT__ ========================================== Log Entry 13: 20 Feb 2011 08:33:42 Alert Level 2: Informational Keyword: Type-02 127002 1208322 Soft Reset Logged by: Baseboard Management Controller; Sensor: System Event 0x204D60D1E60200E0 FFFF027000120300 ========================================== Log Entry 12: 20 Feb 2011 07:14:27 DEREK_SMITH Alert Level 4: TEST ALERT!!!!!!!!!!!!!!!!

I got this working better that halfway, and its usable. Any other help is welcome! `while ( defined( $_ = <$Rlog> )) { s/^Alert Level\s0*(?:[3-9]\|\d{2,})/DEREK\n$&\nSMITH\n/s; } continue { print $_; } __OUT__ ========================================== Log Entry 11: 13 Feb 2011 07:24:32 DEREK Alert Level 5 SMITH : TEST ALERT!!!!!!!!!!!!!!!!!!!!
