Understood. In fact that is what I thought, it is my bad that I posted that code even though it works in HP-UX. Sorry about that.

---------- Post updated at 14:52 ---------- Previous update was at 14:41 ----------

I searched the internet and found that this is a bug in HP-UX awk!!

HP-UX awk gets it wrong and fills FILENAME with the first command line argument.

Here is an example:
Code:
$ awk ' BEGIN { print FILENAME } ' f=10 inputfile1
f=10

tau2otf [-n streams] [-nomessage] [-v] DESCRIPTION
This program is generated when TAU is configured with the -otf=<otf_dir> option. The tau2otf trace converter takes a TAU formatted tracefile (*.trc) and a TAU event description file (*.edf) and produces an output trace file in the Open Trace Format (OTF). The user may specify the number of output streams for OTF. The input files and output file must be specified in that order. TAU traces should be merged using tau_merge prior to conversion. OPTIONS
-n streams Specifies the number of output streams (default is 1). -nomessage Suppresses printing of message information in the trace. -v Verbose mode sends trace event descriptions to the standard output as they are converted. EXAMPLES
The program must be run with the tau trace, tau event and otf output files specified in the command line in that order. Any additional arguments follow. The following will produced an OTF file, a pp.otf and other related event and definition files, from the TAU trace and event files merged.trc and tau.edf trace file: tau2otf merged.trc tau.edf app.otf SEE ALSO
