These are possible output formats for ps h -eo etime
21-18:26:30 15:28:37 48:14 00:01
How to parse them into seconds?
- Please assume at least 3 digits for the days part as I don’t know how long it can be.
- The output will be
egreped
to one only line so no need for a loop.

Answer
With awk:
#!/usr/bin/awk -f BEGIN { FS = ":" } { if (NF == 2) { print $1*60 + $2 } else if (NF == 3) { split($1, a, "-"); if (a[2] != "" ) { print ((a[1]*24+a[2])*60 + $2) * 60 + $3; } else { print ($1*60 + $2) * 60 + $3; } } }
Run with :
awk -f script.awk datafile
Output:
1880790 55717 2894 1
And finally, if you want to pipe to the parser, you can do something like this:
ps h -eo etime | ./script.awk
