Save current directory in variable using Bash? - bash

Question

What I'm trying to do is find the current working directory and save it into a variable, so that I can run export PATH=$PATH:currentdir+somethingelse. I'm not entirely sure if they have a variable that contains cwd by default.
How do I save the current directory in variable using Bash?

Answer 1

This saves the absolute path of the current working directory to the variable cwd:
cwd=$(pwd)
In your case you can just do:
export PATH=$PATH:$(pwd)+somethingelse

Answer 2

I have the following in my .bash_profile:
function mark {
export $1=`pwd`;
}
so anytime I want to remember a directory, I can just type, e.g. mark there .
Then when I want to go back to that location, I just type cd $there

Answer 3

current working directory variable ie full path /home/dev/other
dir=$PWD
print the full path
echo $dir

Answer 4

Your assignment has an extra $:
export PATH=$PATH:${PWD}:/foo/bar

Answer 5

for a relative answer, use .
test with:
$ myDir=.
$ ls $myDir
$ cd /
$ ls $myDir
The first ls will show you everything in the current directory, the second will show you everything in the root directory (/).

Answer 6

On a BASH shell, you can very simply run:
export PATH=$PATH:`pwd`/somethingelse
No need to save the current working directory into a variable...

Answer 7

One more variant:
export PATH=$PATH:\`pwd`:/foo/bar

Answer 8

You can use shell in-build variable PWD, like this:
export PATH=$PATH:$PWD+somethingelse

Answer 9

Similar to solution of mark with some checking of variables. Also I prefer not to use $variable but rather the same string I saved it under
save your folder/directory using save dir sdir myproject and go back to that folder using goto dir gdir myproject
in addition checkout the workings of native pushd and popd they will save the current folder and this is handy for going back and forth. In this case you can also use popd after gdir myproject and go back again
# Save the current folder using sdir yourhandle to a variable you can later access the same folder fast using gdir yourhandle
function sdir {
[[ ! -z "$1" ]] && export __d__$1="`pwd`";
}
function gdir {
[[ ! -z "$1" ]] && cd "${!1}";
}
another handy trick is to combine the two pushd/popd and sdir and gdir wher you replace the cd in the goto dir function in pushd. This enables you to also fly back to your previous folder when making the jump to the saved folder.
# Save the current folder using sdir yourhandle to a variable you can later access the same folder fast using gdir yourhandle
function sdir {
[[ ! -z "$1" ]] && export __d__$1="`pwd`";
}
function gdir {
[[ ! -z "$1" ]] && pushd "${!1}";
}
