2. pwd
To see where we are, we can
print working directory, which returns the path of the directory in which we currently reside:
$ pwd
Sometimes in a script we change directories, but we want to save the directory in which we started.
We can save the current working directory in a variable with
command substitution:
d=$( pwd ) # save cwd
cd /somewhere/else # go somewhere else
# do something else
cd $d # go back to where the script originally started
If you want to print your working directory resolving symbolic links:
$ readlink -m .
