[Solved] Help needed to have changing value to the command prompt string variable PS1
Hi,

I am using git bash terminal window to do git operations. I have set the prompt string variable PS1 in the ~/.bashrc file as follows:
Code:
export PS1="[$PWD $(git branch | grep '*') $] "

This is intended to show me the current git branch's name which is active as part of the prompt string. But, the problem is when I do a git checkout command to change to some other branch in the terminal, this variable's value is not getting updated and still showing the old one.

Please help me with your suggestions.

git-symbolic-ref

GIT-SYMBOLIC-REF(1)						    Git Manual						       GIT-SYMBOLIC-REF(1)

NAME

       git-symbolic-ref - Read, modify and delete symbolic refs

SYNOPSIS

       git symbolic-ref [-m <reason>] <name> <ref>
       git symbolic-ref [-q] [--short] <name>
       git symbolic-ref --delete [-q] <name>

DESCRIPTION

       Given one argument, reads which branch head the given symbolic ref refers to and outputs its path, relative to the .git/ directory.
       Typically you would give HEAD as the <name> argument to see which branch your working tree is on.

       Given two arguments, creates or updates a symbolic ref <name> to point at the given branch <ref>.

       Given --delete and an additional argument, deletes the given symbolic ref.

       A symbolic ref is a regular file that stores a string that begins with ref: refs/. For example, your .git/HEAD is a regular file whose
       contents is ref: refs/heads/master.

OPTIONS

       -d, --delete
	   Delete the symbolic ref <name>.

       -q, --quiet
	   Do not issue an error message if the <name> is not a symbolic ref but a detached HEAD; instead exit with non-zero status silently.

       --short
	   When showing the value of <name> as a symbolic ref, try to shorten the value, e.g. from refs/heads/master to master.

       -m
	   Update the reflog for <name> with <reason>. This is valid only when creating or updating a symbolic ref.

NOTES

       In the past, .git/HEAD was a symbolic link pointing at refs/heads/master. When we wanted to switch to another branch, we did ln -sf
       refs/heads/newbranch .git/HEAD, and when we wanted to find out which branch we are on, we did readlink .git/HEAD. But symbolic links are
       not entirely portable, so they are now deprecated and symbolic refs (as described above) are used by default.

       git symbolic-ref will exit with status 0 if the contents of the symbolic ref were printed correctly, with status 1 if the requested name is
       not a symbolic ref, or 128 if another error occurs.
