I am creating a shell script (A) which is menu driven and in turn calls another shell scripts (X) depending on the selection. X has a list of commands which runs batch jobs in auto mode.
Content of X
I want to be able to resume directly from A if say a job XHRPBYOW has failed.
The program should "prompt" after it has failed if I want to resume from the last failed job. Upon entering my choice it should resume from like (2 in example) and continue.
Is it possible to do so ? If yes how ?
Thank you for your time.
Your response is much appreciated.

Hi everybody,
I am wondering if there is any tool or website out there which can track who is viewing my resume. It is very frustrating when you send your CV or Cover Letter and you receive no feedback from the company, you don't even know if they have checked it out.
Thanks for your help (1 Reply)

In our directory there are too many files, & if I try to execute mv *.gz or rm *.l command it fails, providing error string as - 'arg list too long'. This doesnt happen always, is there any way we know, limit on the rm & mv command so we can take care of this failure in future executions ? (9 Replies)
I have a script that occasionally has a command here and there that fails and I would like to set my script up to just re run the command if the exit code is 1.
Is there a simple way to do that without if/thens or redirecting to the command again? (5 Replies)
Hi!
I have this situation with 3 shellscripts.
One is a "startscript" that simply calls other scripts. This one is scheduled with cron to run at regular intervals. That script runs what I'll refer to as Script 1.
Script 1 in turn runs script 2 (import_catalogs_buyer.sh)
Sometimes, seemingly... (2 Replies)

I would like to get pm-suspend (or any other suspend method) working for a small new desktop computer. It is based on a Zotac GF-8200 ITX motherboard and an AMD Athlon II X@ 240 CPU using ArchLinux x86_64.

Hi, I put a for loop in a script to eject backup tapes from the robot. The command echo' output goes to the log file without problem, but command vmchange's output does not go to the log file although it's working fine. It still displays on the screen. I've tried '2>&1 1>$log', but nothing changed.... (5 Replies)
Sorry if this is the wrong place for this. I haven't done UNIX Admin in a long time and am trying to update the utilities on a Solaris server so that I can get Apache 2.4.25 installed.

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
