in reply to Simple awk question

How about echo $variable | perl -nae 'print $a[0]' or possibly perl -e 'print((split /\s+/, "'$variable'")[0])' ?


Very many thanx to LanX - modifed 2nd suggestion to correct parenthesis, but ignored nested quotes comment since they are most definitely deliberate - without them, perl would split the string '$variable' whereas with them, the shell expands the shell variable and perl then splits that string.

A user level that continues to overstate my experience :-))

    perl -e 'print (split /\s+/, "'$variable'")[0]'

    nested quotes? :)


    and the brackets belong to print , (...)[0] won't work.
