We can also get user_id (user#) from v$session

@rajus19

Thats why its always good to explain your requirement properly in your very first post.

[oracle@localhost scripts]$ cat > user_id.sh
# Unix user id
uname="$1"
uid=`grep \^$uname /etc/passwd | awk -F ":" ' { print $3 }'`
echo $uid
[oracle@localhost scripts]$ chmod +x user_id.sh
[oracle@localhost scripts]$ ./user_id.sh tarun
502

instead of two process,

here is a simpler one,

awk -F":" ' /<loginname>/ {print $3}' /etc/passwd

we can get the info using the simple cut and grep utility

#name.sh
grep -i $1 /etc/passwd|cut -f 3 -d ":"

explanation: we are selecting the field #3 and using the : as the delimiter to get the uid.

or if you just run it with login name:

grep -i oracle /etc/passed|cut -f 3 -d ":"

now run it after chmod +x name.sh

name.sh oracle
