I tried to put the history line number and the date into the file with one command, and failed. Can't figure out how to get the date variable substituted for the last space captured.
history | tail -1 | sed -e 's/.\{7\}/&/g' | head -1 | sed 's/ $/$date/'
Result was:
729 $date

In the awk below, what I am attempting to do is check each line in the tab-delimeted input, which has ~20 lines in it, for a keyword
SVTYPE=Fusion. If the keyword is found I am splitting $3 using the . (dot) and reading the portion before and after the dot in an array a.

devel::calltrace
Devel::CallTrace(3pm) User Contributed Perl Documentation Devel::CallTrace(3pm)NAME
Devel::CallTrace - See what your code's doing
SYNOPSIS
#!/usr/bin/perl -d:CallTrace
package foo;
sub bar {
print "bar
";
baz(); }
sub baz {
print "boo
"; }
foo::bar();
RATIONALE
There are a number of perl modules in the CPAN that are designed to trace a program's execution as it runs. Each uses a different trick to
do its job, but none of them quite met my needs. The technique this module uses is quite simple and seems to be quite robust.
DB::sub
perl will automatically call DB::sub on each subroutine call and leave it up to us to dispatch to where we want to go.
Devel::CallTrace::called
This routine is called with two parameters:
DEPTH
The integer "depth" that this call is being called at.
PARAMS
A reference to the routine's @INC
To get at the subroutine that was being called, have a look at $DB::sub
BUGS
It uses the debugger. How could it not have bugs?
SEE ALSO
perldebguts, DB, a licensed therapist.
trace - Uses source filters. Scares me.
Devel::TraceCalls - Very robust API. The code seems to do all sorts of scary magic
Debug::Trace - Uses symbol table magic to wrap your functions.
Devel::TRaceFuncs - Requires developers to instrument their source files.
