Code:
awk '/Done/ {print $2; exit}' Ar_b3lyp_pv5z.out

and see what you get. I suspect you get nothing. In that case, play with this line awk statment until it produces what you want. Duplicate your efforts on the other line that creates col4. Dont forget to add the | read col3 and read | col4 statements back onto the line.

If you know what the values are supposed to be anyway, hardcode them in, skip the awk for now example:
Code:
col3=99999
#awk '/Done/ {print $2; exit}' Ar_b3lyp_pv5z.out | read col3

The leading # character comments out the line. Repeat this for the col4 line.

It seems when I run the awk '/Done/ {print $5; exit}' Ar_b3lyp_pv5z.out in the command line I do get my one value that I want to repeat 101 times. But when I run the entire script everything is printed except for columns 3 and 4.

Any thoughts. Thanks.

Also I don't know if you care or not but this is technically not my work but yours so I should cite your name as a reference. That's up to you.

Chemist Needs Help part II

Hello friends, I was wondering if you can help me with probably a simple function to you all: the sample looks and has this format. I was wondering how I could extract the first and second column starting including the line 'E/N and Ko' and not stop until there are no more lines. Thank you for... (5 Replies)

shevek::process(3)					     Library Functions Manual						shevek::process(3)

NAME

       shevek::process -

       Create a process, optionally connection its standard in- and output streams to the calling program.

SYNOPSIS

       #include <process.hh>

       Inherits shevek::refbase.

   Public Member Functions
       Glib::RefPtr< shevek::fd > in ()
	   The standard input pipe, if it was requested.
       Glib::RefPtr< shevek::fd > out ()
	   The standard output pipe, if it was requested.
       Glib::RefPtr< shevek::fd > err ()
	   The standard error pipe, if it was requested.
       pid_t pid ()
	   The process ID.
       ~process ()
	   The destructor. This kills the process if it was still running.

Member Function Documentation
   static std::string shevek::process::run (std::string const &command, std::string const &sh) [static]
       Run a process and return its output. A convenience function for running a process and catching its standard output in a string. This blocks
       until the process has exited.

   static Glib::RefPtr<process> shevek::process::shell (std::string const &command, boolpipe_stdin = true, boolpipe_stdout = true, boolpipe_stderr
       = true, std::string const &sh = '/bin/sh') [inline, static]
       Run a string with the shell. Note that the process is forked from the shell, and so does not get killed when the process goes away.
