How to find the exit status of

|

2

The exit status of any command can be extracted using "$?"

For eg:-

sipsak -vv -s sip:192.168.1.3
echo $?

--ahamed

First i will run the below:

Then i need to find the exit status of the below portion of the above command:

4 
sipsak -vv -s sip:192.168.1.3 && es=$? || es=$? | awk '/reply received after/ {getline; $0~/SIP/ {print $2}}'
echo $es
5

Not working. I need to save the output of the command in the variable Lois_Answer_Code as well

can you post the output of the below command

 
sipsak -vv -s sip:192.168.1.3

And let us know, what string you want to extract

Want to extract 200 after the "reply received" line"

10 
Lois_Answer_Code=$(sipsak -vv -s sip:192.168.1.3 | awk '/reply received after/ {getline; if($0~/SIP/){print $2}}')
11

And what about the exit status?

12

What shell are you using?

Newer Korn, and Bash, shells have pipefail:

$ ls blah 2>&1 | grep .
ls: blah: No such file or directory
$ echo $?
0

$ set -o pipefail
$ ls blah 2>&1 | grep .
ls: blah: No such file or directory
$ echo $?
2

$ echo ${PIPESTATUS[@]}  # BASH - show the exit status of all commands in the pipeline
2 0
13

You could run it in a subshell and store the exit status in a file until it's needed.

Lois_Answer_Code=$((sipsak -vv -s sip:192.168.1.3; echo $? > status) | grep ... )
sipssak_exit_status=$(cat status)
