Problem description

This note will record: in Bash, the method of urldecode, and related problem handling.

Solution

This code is copied from Stack Overflow.

Function urldecode () {: "${* / + /}"; echo-e "${_ / /% /\\ x}";} function urldecode () {local I = "${* / + /}"; echo-e "${icontrol% /\\ x}";}

The first one is so strangely written that it contains all kinds of Bash knowledge:

1): to prevent "${* / + /}" from being executed as a command

2) $_ represents the last parameter of the previous command, that is, the parsing result of "${* / + /}"

3) $* indicates all the parameters of the incoming command

4) ${pUnip _ blank /} means to replace the + of the variable p with spaces, while ${pAccord _ blank /} means to replace all the + of the variable p with spaces
