Full Discussion: using awk to drive an internal function
Top Forums Shell Programming and Scripting using awk to drive an internal function Post 84259 by quaddriver on Friday 23rd of September 2005 07:58:38 AM

Ok thanks for the response, ..I fear I might not have been clear on the problem.

consider the script 'foo' that looks like this:

#some comments
function f1(){}
function f2() {}

some option/parameter checking

if [single option]
then
f1 $parm1 $parm2
else #multiple option
awk '{ I want to call f1 with $2 and another parm $parm2 }' somefilename
fi

echo "all done"
exit 0

The above is what I meant by an internal function, it was internal to the program, not awk.

when I enclose f1 within the awk construct like thus: awk '{f1($2)}' some file name I get an error like this:

awk: line 0 (NR=1): variable "f1" cannot be used as a function

I should mention this is not on unix or linux per se but rather OMVS (aka Unix Systems Services) under z/OS on an IBM z/800, and seems to be a rather faithful implementation of every API thus far....

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
