cd returns - like every other command - an error level you can use: it is stored in the variable "$?", which is updated after every executed command.
A return value of "0" (also: logical TRUE) means success, while values between 1 and 254 (all of them meaning a logical FALSE) show various error conditions.
You can use this in scripts in the following two ways:
The second variant uses the logical meaning of non-zero being FALSE, the "&&" is a logical "OR": that way, if "command" returns "FALSE", the second command is executed, otherwise not.
I'm receiving an exit code 64 in our batch scheduler (BMC product control-m) executing a PERL script on UX-HP. Can you tell me where I can find a list of exit codes and their meaning. I'm assuming the exit code is from the Unix operating system not PERL. (3 Replies)

lvremove
LVREMOVE(8) System Manager's Manual LVREMOVE(8)NAME
lvremove - remove a logical volume
SYNOPSIS
lvremove [-A|--autobackup {y|n}] [-d|--debug] [-f|--force] [-h|--help] [-v|--verbose] LogicalVolumePath [LogicalVolumePath...]
DESCRIPTION
lvremove allows you to remove one or more inactive logical volumes.
OPTIONS
-A, --autobackup y/n
Controls automatic backup of VG metadata after the change ( see vgcfgbackup(8) ). Default is yes.
-d, --debug
Enables additional debugging output (if compiled with DEBUG).
-f, --force
Force remove without confirmation.
-h, --help
Print a usage message on standard output and exit successfully.
-v, --verbose
Gives verbose runtime information about lvremove's activities.
Example
"lvremove -f /dev/vg00/lvol1" removes that inactive logical volume unconditionally.
DIAGNOSTICS
lvremove returns an exit code of 0 for success and > 0 for error:
1 no logical volume name on command line
2 invalid logical volume name
3 error checking existence of volume group
4 inactive volume group
5 error getting VGDA from kernel
6 error getting status of logical volume from kernel
7 open logical volume cannot be removed
8 error reading VGDA
9 error removing logical volume from VGDA
10 error removing logical volume from kernel
11 error writing VGDA to physical volume(s)
95 driver/module not in kernel
96 invalid I/O protocol version
97 error locking logical volume manager
98 invalid lvmtab (run vgscan(8))
99 invalid command line
ENVIRONMENT VARIABLES
LVM_AUTOBACKUP
If this variable is set to "no" then the automatic backup of VG metadata is turned off.
LVM_VG_MAX_BACKUPS
This variable determines the backup history depth of kept VGDA copy files in /etc/lvmconf. It can be set to a positive number
between 0 and 999. The higher this number is, the more changes you can restore using vgcfgrestore(8).
LVM_VG_NAME
The default Volume Group Name to use. Setting this variable enables you to enter just the Logical Volume Name rather than its com-
plete path.
