Title:
Bash returns unexpected character \001 on string operation
Status in bash package in Ubuntu:
Confirmed
Bug description:
There has been some change between Precise and Trusty that lets this code
snippet behave differently:
Precise:
$ unset f ; f=abcd ; first_char=${f[@]:0:1} ; echo $first_char
a
Trusty
$ unset f ; f=abcd ; first_char=${f[@]:0:1} ; echo $first_char
\001
The solution is to use ${f:0:1} but nevertheless the result on Trusty seems
completely wrong. Where does the \001 even come from?!
