The boxes utility for Linux allows you to render an ascii text box around text. Below is an example.
homer@homer-eME730 19:14:21 ~ $ echo `echo "This is a sentence printed to the terminal."` | boxes /***********************************************/ /* This is a sentence printed to the terminal. */ /***********************************************/ |
This is a useful utility if you want a text box around your message.
Here I am using sed to replace a word in the sentence printed to the terminal.
homer@homer-eME730 19:30:28 ~ $ echo `echo "This is a sentence printed to the terminal."` | sed 's/sentence/paragraph/gi;' This is a paragraph printed to the terminal. |
Print where you are in the dir tree with this command.
homer@homer-eME730 19:30:52 ~ $ echo $DIRSTACK ~ |
Or use pwd.
homer@homer-eME730 19:37:17 ~ $ pwd /home/homer |
How to print the directory tree to the preceding directory with the Linux command line.
homer@homer-eME730 19:39:41 ~/Documents $ echo ${OLDPWD} /home/homer |
And this is the environment variable that will print the value of pwd
.
homer@homer-eME730 19:41:02 ~/Documents $ echo ${PWD} /home/homer/Documents |
