Re^2: Diff'ing dates

I tried the command and this is what I got:

$ echo -e "Sun 09 30 06 42 36 2007\nTue 10 02 06 01 55 2007\n" | perl 
+-MTime::Local -lane"END{print$t}$F[1]--;$t+=($.*2-3)*timelocal@F[5,4,
+3,2,1,6]"
Can't modify single ref constructor in postdecrement (--) at -e line 1
+, near "]--"
syntax error at -e line 1, near "+="
Execution of -e aborted due to compilation errors.

Use single quotes on UNIX-like operating systems: `echo -e "Sun 09 30 06 42 36 2007\nTue 10 02 06 01 55 2007\n" \| \ perl -MTime::Local -lane 'END{print$t}$F[1]--;$t+=($.2-3)timelocal@F +[5,4,3,2,1,6]'` [download] Double quotes cause your shell to interpret e.g. `$t` as a shell variable. --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.

Use the appropriate quotes for your shell. Switch double quotes for single quotes.	[reply]

I figured you had written the one-liner with single quotes anyway. The small monospace text perlmonks use looked like single quotes because I knew I didn't want to interpolate any variables.
