How to escape single quotes within single quoted strings? 19 answers

You cannot escape single quotes inside single quotes that way. It does not work.

Your command is being seen as

sudo lspci -vvv | awk /System peripheral/ {portn=$1} /Status:/ {split($3,a,"M");printf "%sn",a[1]}

which fails.

To place a single quote inside a single quoted string you need to use ''' .

So your command becomes:

bash -c 'sudo lspci -vvv | awk '''/System peripheral/ {portn=$1} /Status:/ {split($3,a,"M");printf "%sn",a[1]}''
