Stop all jobs if error message occurs

Use -stop-on flag to halt all tasks upon encountering an error message. Note: All tasks will be discontinued if any job yields a message indicating a stop condition.

./threadme -cmd 'bash sendmail.sh {{LINE}}' -f customers.txt -stop-on 'Error:'

[1/8256] [bash sendmail.sh [email protected]] ==> [Sent: [email protected]]
[3/8256] [bash sendmail.sh [email protected]] ==> [Sent: [email protected]]
[4/8256] [bash sendmail.sh [email protected]] ==> [Error: timeout while sending [email protected]]
> Stop output message found: Error: timeout while sending [email protected]

Keep running while message present

Use -while flag to cease all tasks when a success message is absent from any of the jobs. Note: All jobs will be terminated if the message differs for even a single job.

./threadme -cmd 'bash sendmail.sh {{LINE}}' -f customers.txt -while 'Sent:'

Output:

[0/8256] [bash sendmail.sh [email protected]] ==> [Sent: [email protected]]
ERROR: [4/8256] [bash sendmail.sh [email protected]] ==> [Invalid user; exit status 1;]
> No `while message` found: Invalid user; exit status 1;
> Stopping all workers!
> Duration: 7.03404163s 

Use different interpreter

Use -interpreter flag to change command interpreter. By default it's from variable$SHELL.

Have $RANDOM value

# `/bin/bash`
./threadme -cmd 'echo "$USER $RANDOM"' -n=1
# [0/1] [echo $USER $RANDOM] ==> [bobiverse 31459]

Don't have $RANDOM value

./threadme -cmd 'echo "$USER $RANDOM"' -n=1 -interpreter=/bin/sh
# [0/1] [echo $USER $RANDOM] ==> [bobiverse]
