Finding a path like /dir1/dir1
I have a script that asks user to input a path like this:

Code:
echo "please input path"
read path

This works just fine but I want to make sure that the user inputs the path as /xyz/xyz

In other words, I want to make sure that they use a forward slash for the first part of the path with NO forward slash at the end of the second path. I want to print an error message if they enter it incorrectly. I assume I could use a test condition beginning like this as a start:

Code:
tryme=/dir1/dir1/
#if [[ $tryme == '^\/*\/.*[\/]$' ]]; then echo "error";else echo "no error";fi#

However grep correctly matches /dir/dir/ when I use this expression but not the test expression. What am I doing wrong? If the path is /dir1/dir1 "error" should be displayed.

NAME

       dircmp - directory comparison

SYNOPSIS

       dircmp [-ds] [-w n] dir1 dir2

DESCRIPTION

       The  dircmp  command  examines dir1 and dir2 and generates various tabulated information about the contents of the directories. Listings of
       files that are unique to each directory are generated for all the options. If no option is entered, a list is output indicating whether the
       file names common to both directories have the same contents.

OPTIONS

       The following options are supported:

       -d      Compares  the  contents	of  files with the same name in both directories and output a list telling what must be changed in the two
	       files to bring them into agreement. The list format is described in diff(1).

       -s      Suppresses messages about identical files.

       -w n    Changes the width of the output line to n characters. The default width is  72.

OPERANDS

       The following operands are supported:

       dir1    A path name of a directory to be compared.
       dir2

USAGE

       See largefile(5) for the description of the behavior of dircmp when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect the execution of dircmp: LC_COLLATE,	LC_CTYPE,  LC_MES-

EXIT STATUS

       The following exit values are returned:

       0     Successful completion.

       >0    An error occurred. (Differences in directory contents are not considered errors.)
