Hi,
I have a script which does something like the below:
Code:
execute_some_script.sh $arg1 $arg2 `exec-some-cmd`
if [ $? -eq 0 ] then;
do something
else
do something else
fi
However, during some cases, there is an error saying:
line xxx: [: too many arguments
at the line number which has the if statement. The script which is getting called is actually an expect script. Anyway, I am really confused about how its possible for $? to return multiple values. Can someone please help?
Sys: HP-UX 9000
In the calling script how do I 'read' the return/exit value of a called script?:confused:
THX in advance for any assistence.:) (1 Reply)
I think the $? returns 0 if the last issued command was successful and otherwise if not. But does anyone knows the value list that may be returned ? (or it is only zero/one ? )
Thanks in advance,
Abrahao. (3 Replies)

guards
GUARDS(1) User Contributed Perl Documentation GUARDS(1)NAME
guards - select from a list of files guarded by conditions
SYNOPSIS
guards [--prefix=dir] [--path=dir2:dir2:...] [--default=0|1] [-v|--invert-match] [--list|--check] [--config=file] symbol ...
DESCRIPTION
The script reads a configuration file that may contain so-called guards, file names, and comments, and writes those file names that satisfy
all guards to standard output. The script takes a list of symbols as its arguments. Each line in the configuration file is processed
separately. Lines may start with a number of guards. The following guards are defined:
+xxx Include the file(s) on this line if the symbol xxx is defined.
-xxx Exclude the file(s) on this line if the symbol xxx is defined.
+!xxx Include the file(s) on this line if the symbol xxx is not defined.
-!xxx Exclude the file(s) on this line if the symbol xxx is not defined.
- Exclude this file. Used to avoid spurious --check messages.
The guards are processed left to right. The last guard that matches determines if the file is included. If no guard is specified, the
--default setting determines if the file is included.
If no configuration file is specified, the script reads from standard input.
The --check option is used to compare the specification file against the file system. If files are referenced in the specification that do
not exist, or if files are not enlisted in the specification file warnings are printed. The --path option can be used to specify which
directory or directories to scan. Multiple directories are eparated by a colon (":") character. The --prefix option specifies the location
of the files.
