This is actually quite a straight forward process, I have used this several times for long shell scripts. Normally I would break the process into a number of component parts, then allocate each to a sub section of a shell. On completion of each section or sub section I write a file in "/tmp" with a numeric value in it, the shell script accepts a number of arguments. With one being to start where the shell finished last time, this is identified by reading the contents of the file in "/tmp".
Thank you for the response.
I was reading about makefile and it seems to me it is about compiling a program.
You can use makefiles for anything. It is a list of what files are used to create what files, and what programs are used to create them. It can start in the middle, by seeing what files have already been created.
I don't suppose, on the third try, you could actually answer my question?
Is there a file which is created on success but not created on failure? Yes, or no?
Here is an example, written on the assumption your programs create no files.
Code:
# Named Makefile, in the current directory
file4:file3
./sqr.ksh axpyi035_sf axpyi035_sf.par $1 $2 XHRPPYA4;
touch file4
file3:file2
./sqr.ksh axbni061 axbni061.par $1 $2 XHRPBYOX;
touch file3
file2:file1
./sqr.ksh axbni062 axbni062.par $1 $2 XHRPBYOW;
touch file2
file1:
# Code to run program1 here
# Leave the 'touch', Make needs it to track
./sqr.ksh axhri051_sf axhri051_sf.par $1 $2 XHRPPYOV;
touch file1
clean:
rm -f file1 file2 file3 file4
When you run make, it will attempt to create file1 through file5 in that order, by running the commands you tell it to. If there is an error, it will detect the nonzero return code and stop in the middle. Next time you run it, it will remember where it left off by what file1...file5 files have and haven't been created.
Run 'make clean' to remove the files and start over from the beginning.
NOte that the eight leading spaces are actually tabs and must be tabs for make to work.
Here is the start screen from a script that I run to configure Solaris Zones, is this the type of thing that you are looking for?

Some of the sections have more depth as well, in this script there are around 6000 lines. Is this the type of thing that you are looking for?
@Coronoa...thank you again.
The log file is created no matter what , whether the command is successful or not.
How do I tell the program to resume from say "file 5" ?

That's what the 'touch' is for in the makefile, to create flag files on success to remember where it left off.
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.

Hi, I put a for loop in a script to eject backup tapes from the robot.

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 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)
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)

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)
