[SOLVED] Slackware64-14.2 script problem

worsel · 08-24-2016, 11:59 PM

Had an accident about 10 days ago. Lost my home partition.
It was mostly backed up, so nothing important was lost.

After rebuilding, I found I could not run scripts, except in my home directory,
even if I owned the external directory.

Symptoms:
Run a bash script as ./<script> and all that happens is "Permission denied"

Run it as "bash <script>" (or "sh <script>" and it will run if there are no
functions in the script. Any function and again "Permission denied"

A google search turned up a similar problem in Slackware13, which was caused
by wrong permissions in glibc files, but a careful comparison with the file
permissions vs permissions shown in the manifest uncovered no problems there.

If anyone has any idea of what is wrong, please give me a clue.

TIA,

Worsel

what about the permissions of that files "-rwxr-xr-x" ?

what do you mean with functions ? functional script elements or calling to other scripts ?

what about your PATH and /etc/profile.d/ are there any changes ...

/etc/profile ...

.bash_profile or .bashrc ... and so on ?

hope you may get an idea ....

Did you have to re-create your user? If yes, is the UID of your user the same as before?

Sorry to be so long getting back to this, but I've had a few external problems,
mostly a grandson in the hospital with a ruptured appendix. He's out and healing
now, so I can get back to other things.

I have found the problem. Somehow my /etc/fstab file became corrupted. Visually it was
okay, but some partitions were mounted with wrong partions, as shown below:

Quote:

/dev/sda9 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sdb1 on /home type ext4 (rw)
/dev/sda1 on /boot/efi type vfat (rw)
/dev/sdc1 on /home/photos type ext4 (rw,noexec,nosuid,nodev) [PHOTOS]
/dev/sdc2 on /mnt/repos type ext4 (rw,noexec,nosuid,nodev) [REPOSITORY]
/dev/sdg1 on /mnt/sfs_basic type ext4 (rw,noexec,nosuid,nodev) [SFS_BASIC]
/dev/sdf1 on /mnt/backup type ext4 (rw,noexec,nosuid,nodev) [BACKUP]
/dev/sda5 on /mnt/lfs type ext4 (rw,noexec,nosuid,nodev) [LFS]
/dev/sda6 on /mnt/sfs type ext4 (rw,noexec,nosuid,nodev) [SFS]
/dev/sde1 on /mnt/xfr type ext4 (rw,noexec,nosuid,nodev) [XFR]
/dev/sdd1 on /home/Data1 type ext4 (rw,noexec,nosuid,nodev) [DATA1]
/dev/sdd2 on /home/Data2 type ext4 (rw,noexec,nosuid,nodev) [DATA2]
/dev/sdd3 on /home/Data3 type ext4 (rw,noexec,nosuid,nodev) [DATA3]
gvfsd-fuse on /home/jeg/.gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,user=jeg)

I edited fstab, retyping several lines, then rebooted. Now "mount -l" shows this:

gvfsd-fuse on /home/jeg/.gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,user=jeg)

REPOSITORY, LFS, and SFS partitions now allow scripts to run normally.
I'll mark this thread as closed.

Thanks to those who offered help!
