Here’s my favorite Linux prompt.
PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' |
Add to end of your .bashrc to make it permanent.
Tar Commands
Here are two important tar commands on how to create and extract a tar.gz file.
Create a tar gzip file called “project.tar.gz” of a directory called “foo.”
tar -cvzf project.tar.gz foo |
Untar the “project.tar.gz” file to a directory called bar.
tar -zxvf project.tar.gz bar |
Get Directory Size
Here’s how to get the size of a directory.
du -sh /var/www |
Output:
2.1GB /var/www |
Size of the directories and files one level down.
du -sh /var/www/* |
Sort with biggest files from top to bottom.
du -sh /var/www/* | sort -rh |
Top 5 biggest files from top to bottom.
du -sh /var/www/* | sort -rh | head -5 |
