Data Seeking for help in writing shell
Hi All,

I got a problem and stuck to filter a log file, called it as "sample.log". This "sample.log" file is being generated by "script A". The "sample.log" look like below:

Code:
:FORMATDATE_FORMATTIME:CmdArg->:SomeDoce:SomeFormatDocument:
:FORMATDATE_FORMATTIME:imprtcp succeeded.
:FORMATDATE_FORMATTIME:imprttyp completed.
:FORMATDATE_FORMATTIME:fdcode2 failed
::
::...........................
:FORMATDATE_FORMATTIME:CmdArg->:SomeDoce:SomeFormatDocument:
:FORMATDATE_FORMATTIME:imprtcp succeeded.
:FORMATDATE_FORMATTIME:imprttyp completed.
:FORMATDATE_FORMATTIME:DocCode = yadayada(00)
:FORMATDATE_FORMATTIME:Document type is yada.
:FORMATDATE_FORMATTIME:Document not paginated or not text.
:FORMATDATE_FORMATTIME:yada yada succeeded.
:FORMATDATE_FORMATTIME:yada yada succeeded, size=1248.
:FORMATDATE_FORMATTIME:nimport succeeded.

What i try to do is,Since the "sample.log" is actively growing up. i need to

1) Grep the the value failed and also all the required data. i should get like below:-
Code:
:FORMATDATE_FORMATTIME:CmdArg->:SomeDoce:SomeFormatDocument:
:FORMATDATE_FORMATTIME:imprtcp succeeded.
:FORMATDATE_FORMATTIME:imprttyp completed.
 :FORMATDATE_FORMATTIME:fdcode2 failed

2) and email it to the me as an alert.

P/S this script will run in cron to actively monitor the "failed" data.
May be somebody cay help me on figure it out how can i do this.

Currently what i have is:

1) tail -f sample.log | grep failed >> samplelog.failed
## but i stuck at here because tail -f cannot output to other files, i tried but failed, no output has been generate.

2)
test=$(cat samplelog.failed | cut -d: -f-2)
cat sample.log | grep $test: | /usr/bin/mailx -s "Subject" to@somebody


Thanks for your helping in here.

rcsfreeze

RCSFREEZE(1)						      General Commands Manual						      RCSFREEZE(1)

NAME

       rcsfreeze - freeze a configuration of sources checked in under RCS

SYNOPSIS

       rcsfreeze [name]

DESCRIPTION

       rcsfreeze assigns a symbolic revision number to a set of RCS files that form a valid configuration.

       The  idea is to run rcsfreeze each time a new version is checked in.  A unique symbolic name (C_number, where number is increased each time
       rcsfreeze is run) is then assigned to the most recent revision of each RCS file of the main trunk.

       An optional name argument to rcsfreeze gives a symbolic name to the configuration.  The unique identifier is still generated and is  listed
       in the log file but it will not appear as part of the symbolic revision name in the actual RCS files.

       A log message is requested from the user for future reference.

       The  shell  script  works  only on all RCS files at one time.  All changed files must be checked in already.  Run rcsclean(1) first and see
       whether any sources remain in the current directory.

FILES

       RCS/.rcsfreeze.ver
	      version number

       RCS/.rcsfreeze.log
	      log messages, most recent first

SEE ALSO

       co(1), rcs(1), rcsclean(1), rlog(1)

BUGS

       rcsfreeze does not check whether any sources are checked out and modified.

       Although both source file names and RCS file names are accepted, they are not paired as usual with RCS commands.

       Error checking is rudimentary.

       rcsfreeze is just an optional example shell script, and should not be taken too seriously.  See CVS for a more complete solution.
