Check user id
Hi,

I am logged in to my unix box with functional id user1.

Code:
myhost://home/user1> id
uid=3748157(user1) gid=238(dev)

I am trying to execute a script hello.sh with user1 and I am passing a PID to hello.sh.

./hello.sh 145633

This pid <145633> is running with user7.

Thus, I need to check if the user executing the script and the user of the pid being passed must be the same, or else the script should terminate instantly with the echo message

Quote:
echo "The user is different than the user of the PID passed"
I would like to code which runs on most / all the operating systems i.e. most generic, thus avoiding OS specific commands as much as possible.

Can you please help ?

quota

quota(1M)						  System Administration Commands						 quota(1M)

NAME

       quota - display a user's ufs file system disk quota and usage

SYNOPSIS

       quota [-v] [username]

DESCRIPTION

       quota  displays	users'	UFS  disk usage and limits. Only the super-user may use the optional username argument to view the limits of other
       users.

       quota without options only display warnings about mounted file systems where usage is over quota. Remotely mounted file	systems  which	do
       not have quotas turned on are ignored.

       username can be the numeric UID of a user.

OPTIONS

       -v    Display user's quota on all mounted file systems where quotas exist.

USAGE

       See largefile(5) for the description of the behavior of quota when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

FILES

       /etc/mnttab    list of currently mounted filesystems

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWcsu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       edquota(1M), quotaon(1M), quotacheck(1M), repquota(1M), rquotad(1M), attributes(5), largefile(5), zones(5)

NOTES

       quota  displays quotas for NFS mounted UFS-based file systems if the rquotad daemon is running. See rquotad(1M). In a zones(5) environment,
       quota displays quotas only for the zone in which it is invoked.

       quota can display entries for the same file system multiple times for multiple mount points. For example,

	 # quota -v user1

       might display identical quota information for user1 at the mount points /home/user1, /home/user2, and /home/user, if all three mount points
       are mounted from the same file system with quotas turned on.
