Try 2 commands

file and what.

doesn´t work!!

file show me just version of PA-RISC, and what show me nothing !!

[Vibhor Kumar Agarwal]

Yes "file" shows that only.

Then I hope that lib doesn't have the version tag associated with it.

Becasue if it had, then it would be displayed by the "what" command.

There might be any other option not in my knowledge

"what" works for lib (.a) but not for object (.o). I believe object file does not contain version information.

What exactly you are looking for?

[Simone Teles da Hora_5]

I´m migrating all of my system to 11i. And my developers can compiler .a or/and .o in 11.00.

[H.Merijn Brand (procura]

'what' should work as well for .o (objects) as for .a (archives/libraries) as for .sl (shared libraries)

what just scans the binary for prefined patters, as used by the SCCS source code control system. Like tags.

Other systems that leave tags are cvs, svk, rcs, ...

If 'what' doesn't give you version info, you can see if your system has 'ident', which tries to grab other known version tags

If you do not have ident, it's easy to write that in perl:

--8<---[code]
#!/usr/bin/perl -n044

# $Header: perl version of ident (RCS) $
# $Date: 13 Oct 1999 $
# $Revision: v 1.0 $
# $Author: H.Merijn Brand $
# $Id: H/HM/HMBRAND $
# $State: Stable $

m/^( Author

):/x and print " $/$_\n";
[/code]-->8---

If all these fail, you can do

# strings file | less

(replace 'less' with your favourite pager)

Enjoy, Have FUN! H.merijn
