How do I break out of a loop in Perl

Question

I m trying to use a break statement in a for loop  but since I m also using strict subs in my Perl code  I m getting an error saying      Bareword  break  not allowed while    strict subs  in use at   final pl   line 154    Is there a workaround for this  besides disabling strict subs    My code is formatted as follows   for my  entry   array       if   string eq  text             break

On a large iteration I like using interrupts  Just press Ctrl   C to quit   my  exitflag   0   SIG INT    sub    exitflag 1     while   exitflag          Do your stuff

For Perl one-liners with implicit loops  using -n or -p command line options   use last or last LINE to break out of the loop that iterates over input records  For example  these simple examples all print the first 2 lines of the input  echo 1 2 3 4   xargs -n1   perl -ne  last if       3  print   echo 1 2 3 4   xargs -n1   perl -ne  last LINE if       3  print   echo 1 2 3 4   xargs -n1   perl -pe  last if       3   echo 1 2 3 4   xargs -n1   perl -pe  last LINE if       3    All print  1 2  The perl one-liners use these command line flags  -e   tells Perl to look for code in-line  instead of in a file  -n   loop over the input one line at a time  assigning it to    by default  -p   same as -n  also add print after each loop iteration over the input  SEE ALSO  last docs last  next  redo  continue - an illustrated example perlrun  command line switches docs  More examples of last in Perl one-liners  Break one liner command line script after first match Print the first N lines of a huge file

Oh  I found it   You use last instead of break  for my  entry   array       if   string eq  text             last

User · Answer

Simply last would work here   for my  entry   array       if   string eq  text             last            If you have nested loops  then last will exit from the innermost loop  Use labels in this case   LBL SCORE        for my  entry1   array1            for my  entry2   array2                if   entry1 eq  entry2      Or any condition                 last LBL SCORE                                     Given a last statement will make the compiler to come out from both the loops  The same can be done in any number of loops  and labels can be fixed anywhere
