I'm in the process of migrating existing script on UNIX server to the LINUX platform.
One of the script that have issues is this one:
After further investigation, this is due to the
portion which mysteriously working when executed manually but not effective when run the whole script.
Error returned was:
So is there anyway to fix this since I need to put asterisk because I would not know what would be the actual file month.
Change:
to:
to fix your immediate problem. However, this will not work if the filename matching pattern INPUT_GIANT_*csv doesn't match any files in the current directory or if it matches more than one file.
Change:
to:
to make your script run faster. Of course since you haven't shown us an actual filename, this is just a guess; but it seems to be a reasonable guess based on the assumption that that line in your current script works on a UNIX system. (Or, if GIANT_MONYYYY isn't referenced later in your script, just get rid of that line.)

Actually I've already fixed it by
Should be OK right? By right, there should be only one INPUT_GIANT_*csv at a time, it's just that the file month and year would be different.
By the way, does anyone knows why is that the
works by manual typing in the terminal but failed with nohup sh?
I would be very surprised if the command:
ever did what you think it did. If you type in that command manually at a terminal while sitting in a directory where one file matching that pattern exists and immediately follow that command with the command:
I think you'll find that it prints:
while the command:
(with the double quotes removed), prints:
where XXX is the string matched by the asterisk in your filename matching pattern.
You haven't shown us what your script does with the variables file, filename, and GIANT_MONYYYY other than the one place that $filename is expanded while setting the variable GIANT_MONYYYY. Without seeing how those variables are used in the rest of your script, it is hard to guess at what might be wrong.
With what you have shown us, it is hard to guess at why your script would work on a UNIX system (other than a Solaris/SunOS UNIX system) if you were using a Korn shell or a bash shell on both your UNIX system and on your Linux system.
What UNIX operating system were you using and what Linux system are you using now?
What shell were you using on the UNIX operating system and what shell are you using on your Linux system now?
Please show us your complete script as it was when it worked on the UNIX system you were using and please show us the complete script as it now appears on your Linux system.
Note that the error message you are getting is saying that when you run the command:
the pattern INPUT_GIANT_*.csv is not matching any existing file. Note also that the pattern used here is not the same pattern that was assigned to the variable filename. (One ends in .csv while the other one ends in csv (without the <period> character.) There is nothing in the command that is failing that refers to any variable. So, why do you think an expansion of the variable filename is your problem? (Or, did you not show us the first 8 lines of the script named debug_GST.sh?)
What output do you get from the command:
at a time when debug_GST.sh fails with the diagnostic you showed us in post #1 in this thread?

Manual typing to the terminal works as expected:

I know it's a problem with that
because it is inside the log temp.rst saying

After fixing the script, the log is empty
Thanks a lot.

You did not run the command:
(with the double quotes around $filename) as I requested. If you had run that command as I requested, you would have seen that the variable filename contains the filename matching pattern you assigned to that variable (i.e., INPUT_GIANT_*csv); not the filename matching that pattern INPUT_GIANT_JUN2016.csv.
You also did not show us your complete script. If you had shown us the original script that produced the diagnostic you showed us in post #1 in this thread:
and line 8 in that script did expand $filename, I would bet that it did so within double quotes like the printf command I asked you to run above using "$filename".
And, although I did have an off-by-one error since I didn't know what your filenames looked like. Your script will run faster if you change the lines:
in the script you showed us in post #1 to:
since it eliminates a subshell invocation and the invocation of two unneeded external utilities (awk and grep).

Before posting questions about Linux hardware, it is a good idea to check the Linux Hardware HOWTO guide (Last Update: 2007-05-22)
