You change your PATH with command:

PATH=/new-path:$PATH

For example here is how to correctly expand the PATH:

$ PATH=/newpath:$PATH
$ echo $PATH
/newpath:/home/rick/bin:/home/rick/.local/bin:/mnt/e/bin:/mnt/e/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin

Here is just one way to break your PATH (by omitting $ prefix):

$ PATH=/brokenpath:PATH
$ echo $PATH
/brokenpath:PATH

If you mess up your PATH usually you can simply close your terminal and reopen it.

Omitting the $ is the mistake made in your question as well. The method to capture PATH to text file is:

echo $PATH > PATH.TXT

To keep a running log of PATH changes you can use:

echo $PATH >> PATH.TXT

PATH is an environmental variable. To set the variable we use β€œPATH=” but to reference it’s contents we need to use β€œ$PATH”.


The PATH variable can be set in many places as outlined in this Q&A: Where is my PATH variable being set?. To discover which files are setting the PATH one of the answers recommends using:

grep --color -H 'PATH=' ~/.bashrc ~/.profile ~/.bash_profile ~/bash.login \
                     ~/.bash_aliases /etc/bash.bashrc /etc/profile \
                     /etc/profile.d/* /etc/environment 2> /dev/null

On my machine the command returns:

/home/rick/.profile:PATH="$HOME/bin:$HOME/.local/bin:$PATH"
/etc/profile.d/apps-bin-path.sh:    export PATH=$PATH:${snap_bin_path}
/etc/profile.d/jdk.sh:export PATH=$PATH:/usr/lib/jvm/java-8-oracle/bin:/usr/lib/jvm/java-8-oracle/db/bin:/usr/lib/jvm/java-8-oracle/jre/bin
/etc/environment:PATH="/mnt/e/bin:/mnt/e/usr/local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"
