.SH NOTES
|
|
.I strace-log-merge
|
|
does not work well with
|
|
.B strace
|
|
logs generated by
|
|
.B strace -tt
|
|
invocation that pass midnight, as those lack the information required
|
|
for the proper sorting.
|
|
Employing the
|
|
.B -ttt
|
|
option in the respective
|
|
.B strace
|
|
invocation should solve the problem.
|
|
.\"
|
|
.SH BUGS
|
|
.I strace-log-merge
|
|
does not perform any checks whether the files specified are in the correct
|
|
format and implies that only files from a single
|
|
.I strace
|
|
session match
|
|
.IR STRACE_LOG ".*"
|
|
glob pattern.
