How to split value from list

[Jenisha T]

Hi 

Could you pls help me with the splitting value from the list. I need to extract first value anil before ('':')

 grep_atm.stdout_lines output below

ok: [localhost] => {

    "msg": "anil:x:500:500:Anil:/home/anil:/bin/bash

"

}

I tried,

- set_fact:      

       user_name: "{{ grep_atm.stdout_lines }}"

        register: user_name.split(':')[0]      

 - debug:

        var: user_name.split(':')[0]

Based on your data, look at this module:

you should either use set_fact, or register. Both doesn't make sense.

Hello Jenisha,

Assuming that you are getting this value from /etc/passwd., try to change you command

 tail -1 /etc/passwd | awk '{split($0,a,":"); print a[1]}'

cut -d : -f 1 is more concise and readable than your awk command.

Otherwise I would really like to know why Jenisha resorts to reading the password file.

user_name: "{{ my_string.split(':')[0] }}"

This is the correct expression, given the data is in the variable "my_string",
wherever it might come from.

In my case cut doesn't work. I m searching for a particular user from a password.

$ grep anil /etc/passwd

[Karl Auer]

so what's wrong with:

USR="jenisha"

FOUND=`grep $USR /etc/passwd | cut -d: -f1`

if [ -z "$FOUND" ] ; then

   echo "No such user: $USR"

else

   # do whatever...

fi

?

Did you try this ?

 user_name: "{{ my_string[0].split(':')[0] }}"

Thank you, everyone, grep followed by cut gave me desired output

[Jenisha T]

This logic works. Thankyou

[Srinivas Naram]

How do we incorporate if-else in set_fact ?
