I have used Automator Application to create application(.app which runs by double clicking). It runs commands which executes command one by one. Every command takes 2-3 minutes. What I want to achieve is show percentage progress after completion of every command.
In above image percentage is always zero. I want to explicitly set progress after completion of every command. I also know this is possible using AppleScript but I want to implement in bash script.
I did this once for a script of mine:
progress() { set -- "$@" "$((100*$1/$2))" "$(($1 == 0 ? -1 : SECONDS*($2-$1)/$1))" printf "%d of %d (%d%%) eta %s sec" "$@" } You pass it 2 parameters:
Your script will look like:
#!/bin/bash progress() { set -- "$@" "$((100*$1/$2))" "$(($1 == 0 ? -1 : SECONDS*($2-$1)/$1))" printf "%d of %d (%d%%) eta %s sec" "$@" } n=10 # you need to hardcode this, the total number of commands to run i=0 command_01; progress $((++i)) $n command_02; progress $((++i)) $n command_03; progress $((++i)) $n command_04; progress $((++i)) $n command_05; progress $((++i)) $n command_06; progress $((++i)) $n command_07; progress $((++i)) $n command_08; progress $((++i)) $n command_09; progress $((++i)) $n command_10; progress $((++i)) $n printf "\nThat took %d sec\n" $SECONDS
