Top Forums Shell Programming and Scripting Whats the meaning of set -e inside the script Post 302578461 by Scott on Thursday 1st of December 2011 02:24:30 PM

According to the man page for bash:

Code:
set -o <option>
...
  errexit Same as -e.
...

Why not just try it?

Code:
[root@vb1 bin]# set -e
[root@vb1 bin]# ls blah
ls: cannot access blah: No such file or directory
Connection to vb1 closed.

Code:
[root@vb1 bin]# cat myScript
set -e
ls blah
echo Hello

[root@vb1 ~]# ./myScript
ls: cannot access blah: No such file or directory
[root@vb1 ~]#

So, it would appear to mean "when there's an error, exit the current process".

NAME
Locale::Msgcat - Perl extension for blah blah blah SYNOPSIS
use Locale::Msgcat; $cat = new Locale::Msgcat; $rc = $cat->catopen(name, oflag); $msg = $cat->catgets(set_number, message_number, string); $rc = $cat->catclose(); DESCRIPTION
The Locale::Msgcat module allows access to the message catalog functions which are available on some systems. A new Locale::Msgcat object must first be created for each catalog which has to be open at a given time. The catopen operation opens the catalog whose name is given as argument. The oflag can be either 0 or NL_CAT_LOCALE (usually 1) which is the recommended value. The catgets message retrieves message_number for the set_number message set, and if not found returns string. The catclose function should be used when access to a catalog is not needed anymore. EXAMPLES
use Locale::Msgcat; $cat = new Locale::Msgcat; unless ($cat->catopen("whois.cat", 1)) { print STDERR "Can't open whois catalog. "; exit(1); } printf "First message, first set : %s ", $cat->catgets(1, 1, "not found"); unless ($cat->catclose()) { print STDERR "Can't close whois catalog. "; exit(1); } The above example would print the first message from the first message set found in the whois catalog, or if not found it would print "not found". AUTHOR
