echo "Making $SYSTEM_NAME as source system for particular script"

#continue with  $SYSTEM_NAME

Mirni.
the code is on the lines 30-35 ,and while running it throws error on different piece of code.

./switch_dist.sh: syntax error at line 41: `(' unexpected

And, at 41st line, i have following statement in place. Looks like while is not working with parenthesis.

41 echo "\nDo you wish to continue...(y/n): \c"

Code:

while read SYSTEM_NAME
do
   case "${SYSTEM_NAME}" in
      "L1"|"L2"|"P1"|"P2")
         echo "\nMaking $SYSTEM_NAME as source system for particular script"

   esac
   echo "\nPlease enter the source system as L1 L2 P1 P2"
done

echo "\nPlease enter the product name FUNDDB/SMF: \c"


Thanks methyl, case statement worked Smilie

GIT-SH-SETUP(1) 						    Git Manual							   GIT-SH-SETUP(1)

NAME
git-sh-setup - Common Git shell script setup code SYNOPSIS
. "$(git --exec-path)/git-sh-setup" DESCRIPTION
This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish scripts and/or are writing new ones. The git sh-setup scriptlet is designed to be sourced (using .) by other shell scripts to set up some variables pointing at the normal Git directories and a few helper shell functions. Before sourcing it, your script should set up a few variables; USAGE (and LONG_USAGE, if any) is used to define message given by usage() shell function. SUBDIRECTORY_OK can be set if the script can run from a subdirectory of the working tree (some commands do not). The scriptlet sets GIT_DIR and GIT_OBJECT_DIRECTORY shell variables, but does not export them to the environment. FUNCTIONS
die exit after emitting the supplied error message to the standard error stream. usage die with the usage message. set_reflog_action set the message that will be recorded to describe the end-user action in the reflog, when the script updates a ref. git_editor runs an editor of user's choice (GIT_EDITOR, core.editor, VISUAL or EDITOR) on a given file, but error out if no editor is specified and the terminal is dumb. is_bare_repository outputs true or false to the standard output stream to indicate if the repository is a bare repository (i.e. without an associated working tree). cd_to_toplevel runs chdir to the toplevel of the working tree. require_work_tree checks if the current directory is within the working tree of the repository, and otherwise dies. require_work_tree_exists checks if the working tree associated with the repository exists, and otherwise dies. Often done before calling cd_to_toplevel, which is impossible to do if there is no working tree. require_clean_work_tree <action> [<hint>] checks that the working tree and index associated with the repository have no uncommitted changes to tracked files. Otherwise it emits an error message of the form Cannot <action>: <reason>. <hint>, and dies. Example: require_clean_work_tree rebase "Please commit or stash them." get_author_ident_from_commit outputs code for use with eval to set the GIT_AUTHOR_NAME, GIT_AUTHOR_EMAIL and GIT_AUTHOR_DATE variables for a given commit. create_virtual_base modifies the first file so only lines in common with the second file remain. If there is insufficient common material, then the first file is left empty. The result is suitable as a virtual base input for a 3-way merge. GIT
