Bash Version: 2.04
Patch Level: 11
Release Status: release

Description:
^^^^^^^^^^^^

 A BASH shell script (e.g. autofs) will NOT execute by doing 
 ./<script> [options]  in the directory it resides.
 
root@koslx2::/usr/bin              (<--- n.b.  any directory but /root will do)
>./myautofs status
./myautofs: ./myautofs: No such file or directory

>head myautofs    
#!/bin/bash
#
# $Id: rc.autofs.in,v 1.4 2000/01/22 22:17:34 hpa Exp $


 HOWEVER!!! it WILL WORK by merely changing the first line to 
 #!/bin/sh   (rather than #!/bin/bash)   ?????


root@koslx2::/usr/bin
>./myautofs~ status
Configured Mount Points:
------------------------
/usr/sbin/automount /kos yp auto.kos rw,hard,suid,intr,rsize=8192,wsize=8192 
/usr/sbin/automount /fserver yp auto.fserver ro,soft,intr,rsize=8192 

Active Mount Points:
--------------------
/usr/sbin/automount /kos yp auto.kos rw,hard,suid,intr,rsize=8192,wsize=8192
/usr/sbin/automount /fserver yp auto.fserver ro,soft,intr,rsize=8192

root@koslx2::/usr/bin
>head myautofs~
#!/bin/sh
#


 This is crazy since in my system BASH and SH are the SAME THING !
 
>ls -l /bin/sh
lrwxrwxrwx    1 root     root            4 Jan 19 13:06 /bin/sh -> bash
 
 
 Plus, it WILL work as a BASH script if I run it in the /root directory, 
 but nowhere else.

 What on earth is going on here ??  Because of this, my  /etc/init.d/network
 script crashes since the BASH script ./ifup in /etc/sysconfig/network-scripts
 is "not found" ???

 The scripts and the directories have the correct permissions.
 
 

Repeat-By:
^^^^^^^^

Get any BASH script and try ./<script> in a directory like /, /etc/ ,
but NOT /root (it works there).



Fix:
^^^^
     That is where you come in ???
    
    

hope you can help, this is driving me batty.

best regards,
