Top Forums UNIX for Dummies Questions & Answers Write (save time) Permission set Post 302851255 by Avishek_rc1 on Saturday 7th of September 2013 10:04:29 PM
Thanks Scott, that was helpful.

I tried it and it worked. The same user account is used by my application too which creates the file.

Now when the application is using the file, it creates the file as rw-r-----

Can you please suggest why the application, when using the same login creates a file with different permission sets.

Appreciate your help on this.

NAME
sg - execute command as different group ID SYNOPSIS
sg [-] [group [-c ] command] DESCRIPTION
The sg command works similar to newgrp but accepts a command. The command will be executed with the /bin/sh shell. With most shells you may run sg from, you need to enclose multi-word commands in quotes. Another difference between newgrp and sg is that some shells treat newgrp specially, replacing themselves with a new instance of a shell that newgrp creates. This doesn't happen with sg, so upon exit from a sg command you are returned to your previous group ID. CONFIGURATION
The following configuration variables in /etc/login.defs change the behavior of this tool: SYSLOG_SG_ENAB (boolean) Enable "syslog" logging of sg activity. FILES
/etc/passwd User account information. /etc/shadow Secure user account information. /etc/group Group account information. /etc/gshadow Secure group account information. SEE ALSO
id(1), login(1), newgrp(1), su(1), gpasswd(1), group(5), gshadow(5). shadow-utils 4.5 01/25/2018 SG(1)
