Bash remove first and last characters from a string

rated 0 times [ 147] [ 0] / answers: 1 / hits: 380940 / 2 Years ago, sat, august 6, 2022, 7:56:11

I have a string like that:

|abcdefg|

And I want to get a new string called in someway (like string2) with the original string without the two | characters at the start and at the end of it so that I will have this:

abcdefg

Is that possible in bash?

You can do

string="|abcdefg|"

string2=${string#"|"}

string2=${string2%"|"}

echo $string2

Or if your string length is constant, you can do

string="|abcdefg|"

string2=${string:1:7}

echo $string2

Also, this should work

echo "|abcdefg|" | cut -d "|" -f 2

Also this

echo "|abcdefg|" | sed 's/^|(.*)|$/1/'
