Bash: Escape Single Quotes ' #bash #escape #single quote

Strong quoting

Strong quoting is very easy to explain:

Inside a single-quoted string nothing(!!!!) is interpreted, except the single-quote that closes the quoting.

echo 'Your PATH is: $PATH'
That $PATH won't be expanded, it's interpreted as normal ordinary text, because it's surrounded by strong quotes.
In practise that means, to produce a text like Here's my test… as a single-quoted string, you have to leave and re-enter the single-quoting to get the character "'" as literal text:

# WRONG
echo 'Here's my test...'

# RIGHT
echo 'Here'\''s my test...'

# ALTERNATIVE: It's also possible to mix-and-match quotes for readability:
echo "Here's my test"
