Full Discussion: Checking whether the entered text is file or not
Top Forums Shell Programming and Scripting Checking whether the entered text is file or not Post 302777459 by Rashid Khan on Friday 8th of March 2013 02:32:10 AM

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...

addgroup

addgroup(8)						      System Manager's Manual						       addgroup(8)

NAME

       addgroup - Adds a new group interactively

SYNOPSIS

       /usr/sbin/addgroup

DESCRIPTION

								      Security Note

       If  you	have  enhanced security installed on your system, you should use the dxaccounts program to add a group. See Security and the dxac-
       counts(8) reference page for more information.

       The addgroup command is an interactive program for adding new groups to the /etc/group file.  The program prompts you for specific informa-
       tion and informs you of its activity and error conditions.

       Only the superuser can execute this command.

       The  program  performs the following tasks: Queries for a new group name.  The default can be chosen by pressing the Return key, which will
       cause the program to exit without adding a new group.  Enter the new group name, 8 characters or less, or Return to exit.  If the new group
       entered	already  exists in the /etc/group file, the program informs you of this and cycles back to the query for a new group name.  If the
       new group entered does not already exist, the program continues.  Queries for a group number (GID) for the new group.  A default GID, which
       is based on previously existing GID's in the /etc/group file, is displayed and can be selected by pressing the Return key.  Enter a new GID
       or accept the default.  If the new GID entered already exists in the /etc/group file, the program informs you of this and  cycles  back	to
       the  query  for	a new group number (GID).  If the new GID entered does not already exist in the /etc/group file, the program uses this GID
       and adds the new group to the /etc/group file.

       At this point, the program ends.

       This interface has been superseded by the groupadd command-line interface, and the Account Manager (dxaccounts) graphical user interface.

RESTRICTIONS

       The group name is limited to eight characters.

EXAMPLES

       Enter a new group name or <Return> to exit: newgroup Enter a new group number [112]:

FILES

       Specifies the command path.  Group file Lock file
