NAME

       strace-log-merge - merge strace -ff -tt output

SYNOPSIS

       strace-log-merge STRACE_LOG

       strace-log-merge --help

DESCRIPTION

       strace-log-merge  merges  the output of strace -ff -tt[t] command, prepending PID to each line and sorting the result using time stamp as a
       key.

OPTIONS

       --help Show program usage and exit.

       STRACE_LOG
	      Output file name prefix of files produced by a strace -ff -tt[t] command.

EXIT STATUS

       0      Success

       Non-zero
	      Error occurred: either no argument specified (in that case a usage is printed), or something went wrong  during  the  processing	of
	      STRACE_LOG.*  files.

USAGE EXAMPLE

       $ strace -o sleepy -ff -tt -e trace=execve,nanosleep 
	       sh -c 'sleep 0.1 & sleep 0.2 & sleep 0.3'

NOTES

       strace-log-merge  does  not work well with strace logs generated by strace -tt invocation that pass midnight, as those lack the information
       required for the proper sorting.  Employing the -ttt option in the respective strace invocation should solve the problem.

BUGS

       strace-log-merge does not perform any checks whether the files specified are in the correct format and implies that only files from a  sin-
       gle strace session match STRACE_LOG.*  glob pattern.

HISTORY

       The initial version of strace-log-merge was written by Denys Vlasenko in 2012.

REPORTING BUGS

       Problems with strace-log-merge should be reported to the strace mailing list at <strace-devel@lists.sourceforge.net>.
