Help needed in calling path file from Perl script.
Hi All,
I need help in accessing a path file (path.xyz_pqr) not having a shell shebang and exporting paths in the following syntax,
export DB_SCRIPT_PATH="/abc/aash/scripts/db_scripts/xyz_pqr"
export SRC_FILES_DIR="/bcd/fdw/incoming/xyz_pqr"
I need to use the path contained in the DB_SCRIPT_PATH variable.
Tried using system, `` and exec also referred to earlier posts like
https://www.unix.com/shell-programmin...ent-shell.html
but could not get it working.
The path.xyz_pqr file works when called using ./path/of/path.xyz_pqr file on the command prompt but not through my perl script.
I am currently working on /usr/bin/sh shell. Please help m ein calling this path file in my Perl script and using the DB_SCRIPT_PATH variable in my Perl script for getting the path stored in it.
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
