Delayed Command Execution

Wait for a specified duration, then execute a Bash command.

Arguments

duration

Time to wait before execution (e.g.,

30s

,

5m

,

1h

,

1h30m

)

command

The Bash command to run after the delay Duration Format Format Example Meaning Xs 30s 30 seconds Xm 5m 5 minutes Xh 1h 1 hour XhYm 1h30m 1 hour 30 minutes XhYmZs 1h5m30s 1 hour 5 min 30 s Workflow 1. Parse Duration Convert the duration argument to seconds: Extract hours ( h ), minutes ( m ), and seconds ( s ) components Calculate total seconds: hours * 3600 + minutes * 60 + seconds Parsing logic: duration = " $1 " seconds = 0

Extract hours

if [ [ $duration =~ ( [ 0 -9 ] + ) h ] ] ; then seconds = $(( seconds + ${BASH_REMATCH[ 1 ]} * 3600 )) fi

Extract minutes

if [ [ $duration =~ ( [ 0 -9 ] + ) m ] ] ; then seconds = $(( seconds + ${BASH_REMATCH[ 1 ]} * 60 )) fi

Extract seconds

if [ [ $duration =~ ( [ 0 -9 ] + ) s ] ] ; then seconds = $(( seconds + ${BASH_REMATCH[ 1 ]} )) fi 2. Execute with Delay For durations up to 10 minutes (600 seconds): Run synchronously using the Bash tool with appropriate timeout: sleep < seconds

&& < command

Set the Bash tool's timeout parameter to at least (seconds + 60) * 1000 milliseconds. For durations over 10 minutes : Run in background using run_in_background: true : sleep < seconds

&& < command

Inform the user the command is running in background and provide the task ID for checking status. 3. Report Result After execution completes: Display command output Report exit status Note total elapsed time Examples Short Delay (Synchronous) User: /delayed-command 5m npm test Parse: 5 minutes = 300 seconds Execute: sleep 300 && npm test (timeout: 360000ms) Report test results Long Delay (Background) User: /delayed-command 1h git commit -m "auto-commit" Parse: 1 hour = 3600 seconds Execute in background: sleep 3600 && git commit -m "auto-commit" Return task ID for status checking Combined Duration User: /delayed-command 1h30m ./deploy.sh Parse: 1h30m = 5400 seconds Execute in background (>600s): sleep 5400 && ./deploy.sh Inform user of background task Error Handling Error Response Invalid duration format Show supported formats and examples Missing command argument Prompt for the command to execute Command not found Report error after delay completes Duration exceeds 24h Warn user and suggest alternative (cron, at)
