Top Forums Shell Programming and Scripting Var in nawk script parse incorrectly Post 302507653 by HexKnot on Thursday 24th of March 2011 11:48:39 AM

Sorry, I guess I'm missing something. I don't see any difference in what you posted and what I'm doing.

Code:
printf "%s\n" ${sNAMES[@]}

## Typo in original post has been fixed. sNames should have been xNames.

By putting parentheses around the names bash recognizes that the contents are an array. I can test this using the following.
Code:
$ xNAMES=( Abigail Alejandro Alex Alton Amos )
$ echo ${xNAMES[0]}
Abigail
$ echo ${xNAMES[1]}
Alejandro
$ echo ${xNAMES[2]}
Alex
$ echo ${xNAMES[3]}
Alton
$ echo ${#xNAMES[@]}
5

My problem is that the following happens when using the awk script.
Code:
xNAMES=( Abigail Alejandro Alex Alton Amos )
$ echo ${xNAMES[0]}
Abigail Alejandro Alex Alton Amos
$ echo ${xNAMES[1]}
$
$ echo ${xNAMES[2]}
$ echo ${#xNAMES[@]}
1
$

Please let me know if I missed something.

Thanks

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.

SEE ALSO
