Only zsh supports nest string manipulation.▼
First ''or'' last character:
<lang bash>str='abcdefg'
echo "${str#?}" # Remove first char
echo "${str%?}" # Remove last char</lang>
echo ${${str#?}%?} # Remove first & last chars▼
First ''and'' last character:
▲: <lang bash>echo ${${str#?}%?} # Remove first & last chars</lang>
: bash and ksh, use substring expansion, from character index 1 for length of (string length) minus 2
: <lang bash>echo "${s:1:${#s}-2}"</lang>
: POSIX shells like dash, need a temp variable
: <lang bash>tmp=${s#?}; tmp=${tmp%?}; echo "$tmp"</lang>
