Full Discussion: Checking whether the entered text is file or not

let me elaborate it a bit..

the path entered by the user is supposed to be something like "$ABCD/defef/geft.txt" and i want to check if anything out of "$ABCD/defef/geft.txt" is mistyped. The script should exit.

and if, only $ABCD or defef or gef.txt is entered by the user, still script should exit.

i tried this



Code:
$Input_filename=$ARGV[0];
	
if (!-e $Input_filename $$ !-d $Input_filename) 
{
	print "the file does not exist, Please enter a valid file name";
	exit;
}


please suggest where i am mistaken...

dsmemberutil(1) 					    BSD General Commands Manual 					   dsmemberutil(1)

NAME

     dsmemberutil -- various operations for the membership APIs, including state dump, check memberships, UUIDs, etc.

SYNOPSIS

     dsmemberutil [-v] [-h] command [options]

DESCRIPTION

     dsmemberutil is a program that implements the membership API calls in a command line utility.

FLAGS

     A list of flags and their descriptions:

     -h      Lists the options for calling dsmemberutil

     -v      Causes dsmemberutil to operate in verbose mode.

COMMANDS

     The action of each command is described below:

     getuuid -ugUGsS value
		 Takes any of the options and returns the associated UUID.

     getid -UGsSX value
		 Takes any of the options and returns the associated UID or GID depending on option provided.

     getsid -ugUGX value
		 Takes any of the options and returns the associated SID.

     checkmembership -uUxs param -gGXS param
		 Returns if a user or group with the associated option is a member of the group.

     flushcache  Flushes the current membership cache.

     Legacy commands such as dumpstate and statistics are gone. See odutil(1) for show cache and statistics operations.

     A list of options available. In some cases -xX and -sS can be used synonymously due to nature of the value.

     -u uid	      Using user with UID

     -U name	      Using user with name

     -s sid	      Using user with SID

     -x uuid	      Using user with UUID

     -g gid	      Using group with GID

     -G name	      Using group with name

     -S sid	      Using group with SID

     -X uuid	      Using group with UUID

EXAMPLES

     Get a user's uuid:
		    % dsmemberutil getuuid -u 501
		    EEA4F2F6-B268-49E7-9C6F-E3C4A37DA4FD

     Get a group's uuid
		    % dsmemberutil getuuid -g 0
		    ABCDEFAB-CDEF-ABCD-EFAB-CDEF00000000

     Get a user's or group's id from a uuid
		    % dsmemberutil getid -X ABCDEFAB-CDEF-ABCD-EFAB-CDEF0000000C
		    gid: 12

     Check a user's membership in a group (using UID and GID)
		    % dsmemberutil checkmembership -u 501 -g 0
		    user is not a member of the group

     Check a user's membership in a group (using names)
		    % dsmemberutil checkmembership -U root -G wheel
		    user is a member of the group
