| I looked closer at the source and all test of the error value are made
| against $! instead of $|.
| This patch fix all occurences i found in update-alternatives and restore
| file openings error messages.
| That had nothing in termn of functionality. I hope users won't be
| disturbed by those new errors .
Please read the perlvar man page.
$OUTPUT_AUTOFLUSH
$| If set to nonzero, forces a flush right away and after
every write or print on the currently selected output
channel.
while for $!:
$OS_ERROR
$ERRNO
$! If used numerically, yields the current value of the C
Ģerrnoģ variable, or in other words, if a system or library
call fails, it sets this variable.
