Location of functions

Question

If I run the declare command it returns some functions

$ declare -F | grep \'f [^_]\'
declare -f dequote
declare -f quote
declare -f quote_readl         


        

Answer 1

To find the file name and line number of a function declaration in bash, use shopt -s extdebug:

$ shopt -s extdebug
$ declare -F quote
quote 143 /usr/share/bash-completion/bash_completion
