Top Forums Shell Programming and Scripting Should I run scripts like sh /absolute_path/to/scriptname.sh or just /absolute_path/to/scriptname.sh Post 302994881 by John K on Wednesday 29th of March 2017 06:57:35 AM

Should I run scripts like sh /absolute_path/to/scriptname.sh or just /absolute_path/to/scriptname.sh

Shell : Linux Bash
OS version : RHEL 6.X, Oracle Linux 6.X

Question1. To execute shell scripts, sometimes I see Linux admins placing sh command before shell scripts like below

Code:
sh /home/appadmin/sync_pending_orders.sh

But, I execute shell scripts like below ie. Just the absolute path

Code:
/home/appadmin/sync_pending_orders.sh

Which is recommended ?

Question2. Similarly, in crontab entries , I see sh being placed before shell script names like below. Is this sh 'prefixing' really needed ?

Code:
[appadmin@ktsappwprg01 ~]$ crontab -l
35 2 * * * /bin/sh /home/appadmin/sync_orders.sh >> /home/appadmin/log/ind_critical.log

25 3 * * * /bin/sh /home/appadmin/sync_pending_orders.sh >> /home/appadmin/log/ind_crtical_2.log

PAPERCONFIG(8)						   Linux Administrator's Manual 					    PAPERCONFIG(8)

NAME
paperconfig - configure the system default paper size SYNOPSIS
paperconfig [ -v,--version ] [ -h,--help ] [ -p, --paper papername | --force ] DESCRIPTION
paperconfig sets the system (or default) paper to be used by tools using the papersize file. It can either ask interactively for the paper to use or be called non-interactively by scripts. When the paper size has been changed, paperconfig notifies other packages of the change by running the scripts in the /etc/libpaper.d directory. OPTIONS
-v,--version Print the version of paperconfig and exit. -h,--help Print help about usage and exit. -p, --paper papername Use papername if possible. If papername is not a valid paper, print an error message and exit. --force Force interactive selection of the system paper even if the actual paper is a valid one. ENVIRONMENT
PAPERCONF Full path to a file containing the paper size to use; this file will be rewritten with the system paper size. FILES
/etc/papersize Contains the name of the system-wide default paper size to be used if the PAPERSIZE variable is not set. /etc/libpaper.d Directory of scripts to run after the paper size has been changed. This package puts no scripts here, but other pack- ages may. AUTHOR
