shell execution problem

harjeet_3 — Sat, 26 Mar 2011 05:36:26 GMT

hello,

That, I use HP-UX ver 10.*

That, daily, I execute one shell present in the "global" folder which is sub-folder of /usr1/usr3, using the following commands.

#cd /usr1/usr3/global
#./ntpatch

Today I did the same but message appears "file not found"

That, I use ll/ls command to get the listing of file(s) in the folder named "global" but it shows ". not found". That folder is sub-folder of /usr1/usr3 folder. but if i use the listing command with full path i.e. "ll /usr1/usr3/global then it shows the list of files present in the "global" folder.

That, In this context I have taken a shutdown and run the fsck command for all the file-system including /usr1, but all is in vain.

In view of the above submission my query is why such strange thing begun to happen. Please help me as it is important shell that i have to execute daily.

thanks in advance

As usual, it can be more helpful to show
actual commands with their actual output,
rather than vague descriptions or
interpretations. Don't _tell_ me what you
did and what happened, _show_ me.

mount
cd [...]
ls -l [...]

>i.e. "ll /usr1/usr3/global" then it shows the list of files present in the "global" directory.

What happens when you do: cksum /usr1/usr3/global/*

Can it find, then read the content of those files?

The shell script must be executable when you type script name. ll will show the script, but to run a script, it must be executable (ie, 755 permissions).

This error message would suggest filesystem corruption. I hope you have good backups.

Did you run a _full_ fsck?

For vxfs-type filesystems, the default is to run a short filesystem check only. When the operating system detects the filesystem is damaged, it places a damage indicator to the superblock, which causes a full fsck to run automatically. But I guess some types of filesystem corruption might go undetected.

If the filesystem type is vxfs and you aren't 100% certain you already ran a _full_ filesystem check on it, please reboot the system to single-user mode and explicitly run a full filesystem check:

fsck -F vxfs -o full /dev/

Any reason you can't unmount it and run fsck(1m) in non-single-user mode?
