Same strings are not equal
Hi there can anyone help me please. I want to make a program to check if the executable file specified by the user exists in the directory.
When I run this program particulary these lines of code does not work:
Code:
if ("$fi" == "$name") then

where It checks whether the specified file is equal to the file in the directory. I thought it might be due to spaces. However, in both cases there is an additional space. So, I think they should be idetical. And question number 2: I made a brake from the loop in if statement can I do it like that???
Code:
#!/bin/csh
 if ($#argv == 1) then
        set name=$1
        set files=`ls`
        set  numfiles=`echo $files | wc -w`
       @ count=1
        while ( $count < $numfiles)
        set fi=`echo $files | cut -f$count -d ' '`
        if (-f $fi && -x $fi ) then
                        set charnum=`echo $fi | wc -c`
                        if ("$fi" == "$name") then
                                echo "I am here 3"
                                echo $fi
                                break
                        endif
        endif
        @ count = $count + 1
        end
endif

Thanks in advance! :-)

run

run(1F)                                                            FMLI Commands                                                           run(1F)

NAME

       run - run an executable

SYNOPSIS

       run [ -s] [-e] [-n] [-t string] program

DESCRIPTION

       The run command runs program, using the PATH variable to find it. By default, when program has completed, the user is prompted (Press ENTER
       to continue:), before being returned to FMLI.  The argument program is a system executable followed by its options (if any).

OPTIONS

       The following options are supported:

       -e                      If -e is specified, the user will be prompted before returning to FMLI only if there is an error condition

       -n                      If -n is specified, the user will never be prompted before returning to FMLI (useful for programs like vi, in which
                               the user must do some specific action to exit in the first place).

       -s                      The  -s  option  means "silent", implying that the screen will not have to be repainted when program has completed.
                               Note that the -s option should only be used when program does not write to the terminal. In addition,  when  -s  is
                               used, program cannot be interrupted, even if it recognizes interrupts.

       -tstring                If -t is specified, string is the name this process will have in the pop-up menu generated by the frm-list command.
                               This feature requires the executable facesuspend (see face(1)) to suspend the process and return to the FMLI appli-
                               cation.

EXAMPLES

       Example 1: Sample output of run command

       Here is a menu that uses run:

       menu="Edit special System files"
       name="Password file"
       action=`run -e vi /etc/passwd`
       name="Group file"
       action=`run -e vi /etc/group`
       name="My .profile"
       action=`run -n vi $HOME/.profile`
