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=$PATH:currentdir+somethingelse
. I'm not entirely sure if they have a variable that contains cwd by default.
How do I save the current directory in variable using Bash?
You can use shell in-build variable PWD
, like this:
export PATH=$PATH:$PWD+somethingelse
Your assignment has an extra $
:
export PATH=$PATH:${PWD}:/foo/bar
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
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}";
}
One more variant:
export PATH=$PATH:\`pwd`:/foo/bar
On a BASH shell, you can very simply run:
export PATH=$PATH:`pwd`/somethingelse
No need to save the current working directory into a variable...
for a relative answer, use .
test with:
$ myDir=.
$ ls $myDir
$ cd /
$ ls $myDir
The first ls
will show you everything in the current directory, the second will show you everything in the root directory (/
).
current working directory variable ie full path /home/dev/other
dir=$PWD
print the full path
echo $dir
