[SOLVED] How to pass a single quote inside of a single quote...

trist007 · 02-09-2011, 06:43 PM

Here's a command I have to monitor my 3 computers in my lan.

Code:

watch 'printf "BSD\n" && ssh bsd ps u && printf "\n" && ssh bsd iostat && printf "\n################################################################################################################################################\n\nCentOS\n" && ssh centos ps u && printf "\n" && ssh centos iostat && printf "\n################################################################################################################################################\n\nDarkstar\n" && ps u && printf "\n" && iostat'

But I'd like to clean it up and make it look like this. However, the perl -e 'print "#"x145' has single quotes which ends up closing the first single quote at watch 'printf.

Code:

watch 'printf "BSD\n" && ssh bsd ps u && printf "\n" && ssh bsd iostat && printf "\n" && perl -e 'print "#"x145' && printf "\n\nCentOS\n" && ssh centos ps u && printf "\n" && ssh centos iostat && prin
tf "\n" && perl -e 'print "#"x145' && printf "\n\nDarkstar\n" && ps u && printf "\n" && iostat'

Any way around that?

Hi,

if you want to escape a single quote inside single quotes you can do it with the following sequence:

Code:

'\''

You actually close the single quote, escape the single quote and then reopen it. Example:

Code:

echo 'quote'\''s'
