Full Discussion: Regex to validate parameter for sleep
Top Forums Shell Programming and Scripting Regex to validate parameter for sleep Post 303025557 by RudiC on Monday 5th of November 2018 12:31:50 PM

man sed:
Quote:
q [exit-code]
Immediately quit the sed script without processing any more input, except that if auto-print is not disabled the current pattern space will be printed. The exit code argument is a GNU extension.
q0 and q1 in above script set the exit code to be evaluated in the if ... fi construct.



Wouldn't it be the time NOW to analyse the regex used in the sed script and try to transform / translate it to a bash regex?


Howsoever, with some experimenting, I found
Code:
while read DA
  do   if [[ "$DA" =~ [^0-9+.]|^[+0.]*$|[.].*[.] ]]
          then echo invalid value for sleep: $DA, $?, ${BASH_REMATCH[0]}
          else echo valid: $DA, $?, ${BASH_REMATCH[0]}
       fi
  done < file

to come close to what you want / need.
