Full Discussion: Check for spaces in input argument!
Top Forums Shell Programming and Scripting Check for spaces in input argument! Post 302887933 by sea on Tuesday 11th of February 2014 05:17:26 PM
Old 02-11-2014
Until now i used either arrays to parse the args (compare item with string '-h') and do action (or set variable) of array(+1), skipping i and i+1 after or even worse (but most used - lazy) hard coded argument positions....

eg - pseudo code - tired:
Code:
i=0
ARGS=($@)
for cur in $(seq 0 1 $#@);do
   ((i++))
   case "${ARGS[$cur]}" in
   "-h") echo "help" ;;
   "-o") echo other
         otherValue=${ARGS[$i]}
         unset ARGS[$i] ARGS[$cur] ;;
   *) echo "no args, or unhandled) ;;
    esac
done

This switch method kind of sounds faster.

Did i understand this properly (simplified?):
We're switching the flag, which is the actual argument trigger/toggle/(lost in translation), while argv[1] is the actual current value to be set as variable?
