How can I make some output bold in Ubuntu terminal
echo "text bold text" text bold text
or the same from
cat my_file
Here's how:
echo -e "text \033[1mbold\033[0m text"
See "Colorizing" Scripts tutorial.
It's not possible to do for cat
that way. cat
will merely print the characters of the file onto standard out. The closest thing I can come up with is the following:
If you put text \033[1mbold\033[0m text
you can do
echo -e `cat test.txt`
Also checkout tput(1). Based on ncurses(3) which is a system abstraction for terminal manipulation (i.e. its purpose is to bring an API which works independent of architecture, OS, terminal, tty, etc.).
Example:
echo "$(tput bold)AHHH$(tput sgr0)"
Hehe, asked 10 years ago; I'm too useful.
You can "cat" a file in bold by doing command substitution.
echo -e "text \033[1m`cat my_file`\033[0m text"
"Command substitution reassigns the output of a command or even multiple commands; it literally plugs the command output into another context."
So the magic part here is
`cat my_file` # or $(cat my_file)

Backticks will be portable to legacy shells, while I prefer to use $()
