zsh wrapper: how to add prefix to the shell command parameters?-CodePudding

For example, I have defined a zsh-script called "myCmd.sh" when I run

myCmd --op1 "/p1/p2" --op2 "/p3/p4" -op3 "a"

it should actually call

Cmd --op1 "/mnt/d/p1/p2" --op2 "/mnt/d/p3/p4" -op3 "a"

In other words, once a path string occurred in the command parameters, the prefix "/mnt/d" will be added, the cmd and other args or parameters will remain the same.

CodePudding user response：

You can use static named directories to have filename expansion produce the desired path, saving you a little typing. For example,

d=/mnt/d

cmd --opt1 ~d/p1/p2 --op2 ~d/p3/p4

is the same as

cmd --opt1 /mnt/d/p1/p2 --op2 /mnt/d/p3/p4

~name, where name is any parameter with a value that starts with /, is expanded to the value of the parameter.

An example:

% echo ~d
zsh: no such user or named directory
% d=/mnt/d
% echo ~d
/mnt/d
