I have a little Bash script which suspends the computer after a given number of minutes. However, I'd like to extend it to tell me what the time will be when it will be suspended, so I can get a rough idea of how long time I have left so to speak.
#!/bin/sh
let SECS=$1*60
echo "Sleeping for" $1 "minutes, which is" $SECS "seconds."
sleep $SECS &&
pm-suspend
The only argument to the script will be how many minutes from now the computer should be suspended. All I want to add to this script is basically an echo saying e.g. "Sleeping until HH:nn:ss!". Any ideas?

Using date. #!/bin/bash # Exercising the 'date' command echo "The number of days since the year's beginning is `date +%j`." # Needs a leading '+' to invoke formatting. # %j gives day of year. echo "The number of seconds elapsed since 01/01/1970 is `date +%s`." #
date +%S. Displays seconds [00-59] date +%N. Displays in Nanoseconds.
Sample shell script to display the current date and time #!/bin/bash now="$(date)" printf "Current date and time %s\n" "$now" now="$(date +'%d/%m/%Y')" printf "Current date in dd/mm/yyyy format %s\n" "$now" echo "Starting backup at $now, please wait..." # command to backup scripts goes here # ...
Found out how.
echo "The computer will be suspended at" $(date --date "now $1 minutes")

On BSD-derived systems, you'd use
date -r $(( $(date "+%s") + $1 * 60 ))
i.e. get the current date in seconds, add the number of minutes, and feed it back to date.
Yeah, it's slightly less elegant.

on linux
SECS=`date "+$s"`
SECS=$(( SECS + $1 * 60 ))
date --date $SECS
