Tried to look for solution, and found something similar but could not adapt the solution for my needs..
I'm trying to match a pattern (in this case "ProcessType")in a logfile, then delete that line and the 4 following lines.
The logfile looks as follows:
Code:
ProcessType: PROCESS_A (0) <---- delete this
SequenceNumber: 8285 <---- delete this <---- delete this
2009 Mar 07 22:04:23:679 0:8285 <---- delete this <---- delete this
ProcessType: PROCESS_A (0)
SequenceNumber: 8286
2009 Mar 07 22:04:23:679 0:8286
ProcessType: PROCESS_B (68)
SequenceNumber: 40689
2009 Mar 07 22:04:23:698 68:40689
DATA that should not be deleted
ProcessType: PROCESS_B (68)
SequenceNumber: 40690
2009 Mar 07 22:04:23:698 68:40690
DATA that should not be deleted
ProcessType: PROCESS_C (93)
SequenceNumber: 36235
2009 Mar 07 22:04:23:829 93:36235
ProcessType: PROCESS_C (93)
SequenceNumber: 36236
2009 Mar 07 22:04:23:829 93:36236
DATA that should not be deleted
I tried this:
Code:
sed -e '/\<ProcessType\>/,/$/d' < log.txt > test
But that only resulted in this:
Code:
2009 Mar 07 22:04:23:679 0:8285
2009 Mar 07 22:04:23:679 0:8286
2009 Mar 07 22:04:23:698 68:40689
2009 Mar 07 22:04:23:698 68:40690
2009 Mar 07 22:04:23:829 93:36235
2009 Mar 07 22:04:23:829 93:36236
2009 Mar 07 22:04:23:945 91:89062

logsave
LOGSAVE(8) System Manager's Manual LOGSAVE(8)NAME
logsave - save the output of a command in a logfile
SYNOPSIS
logsave [ -asv ] logfile cmd_prog [ ... ]
DESCRIPTION
The logsave program will execute cmd_prog with the specified argument(s), and save a copy of its output to logfile. If the containing
directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out. A copy of the output will
also be written to standard output.
If cmd_prog is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in
logfile
logsave is useful for saving the output of initial boot scripts until the /var partition is mounted, so the output can be written to
/var/log.
OPTIONS -a This option will cause the output to be appended to logfile, instead of replacing its current contents.
-s This option will cause logsave to skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of
Header) and control-B (ASCII 002 or Start of Text). This allows progress bar information to be visible to the user on the console,
while not being written to the log file.
-v This option will make logsave to be more verbose in its output to the user.
