I have the permissions to write....
here is the scenario.
I have a shell script which monitors a particular directory for text files, If found it processes the files sequentially (fifo)and uploads data into a database, this shell script is up and running all the time.(where 1=1)
but, some files in this directory have dependency on other files, say I should have two text files to kick the process to upload the data from them into a database.
For some reason if the shell script sees only one file among the two it will not process it until it sees its dependecy (other missing)file in the directory
so as to give preference to the files other than this dependency set , I have added a touch command ( the whole purpose of this is to change the time stamp) and make the fifo logic work out.
but strangely the system is throwing the above error. This functionality was working fine for the last few months
Any idea what might be triggering the system to throw this error..
Thanks for your attention and precious time.
Regards,
Ram

chsh

chsh(1) 						      General Commands Manual							   chsh(1)

NAME

       chsh - change login shell

SYNOPSIS

       chsh [-D binddn] [-P path] [-s shell] [-l] [-q] [-u] [-v] [user]

DESCRIPTION

       chsh  is  used  to  change  the	user login shell.  A normal user may only change the login shell for their own account, the super user may
       change the login shell for any account.

       If a shell is not given on the command line, chsh operates in an interactive fashion, prompting the user  with  the  current  login  shell.
       Enter  the  new	value  to change the field, or leave the line blank to use the current value. Enter none to remove the current value.  The
       current value is displayed between a pair of [ ] marks.

       The only restrictions placed on the login shell is that the command name must be listed in /etc/shells, unless the invoker  is  the  super-
       user, and then any value may be added.  An account with a restricted login shell may not change their login shell.

       This version of chsh is able to change the shell of local, NIS, NIS+ and LDAP accounts , if the permissions allow it.

OPTIONS

       -D, --binddn binddn
	      Use  the	Distinguished  Name binddn to bind to the LDAP directory.  The user will be prompted for a password for simple authentica-
	      tion.

       -P, --path path
	      The passwd file is located below the specified directory path. chsh will use this files, not /etc/passwd.  This is useful for  exam-
	      ple  on  NIS master servers, where you do not want to give all users in the NIS database automatic access to your NIS server and the
	      NIS map is build from special files.

       -s, --shell
	      Specify your login shell.

       -l, --list-shells
	      Print the list of shells listed in /etc/shells and exit.

       -q, --quite
	      Don't be verbose.

       -u, --usage
	      Print a usage message and exit.

	   --help
	      Print a more verbose help text and exit.

       -v, --version
	      Print version information and exit.

FILES

       /etc/passwd - user account information
       /etc/shells - list of valid login shells

SEE ALSO

       chfn(1), passwd(5), shells(5)
