How can I alias a command that uses custom input in terminal?
For example, let's say a command
$ oj d https://codeforces.com/contest/1348/problem/A
In this command 1348 and 'A' can change. How can I achieve this?
Something like I can alias the whole command as,
$ oj d 1348 A
such that it can act like same.
Aliases do not accept parameters. You need to write a function or a separate script.
Bash/Zsh function:
Define the following function in your .bashrc/.zshrc depending on what interactive shell you use:
mycommand() {
oj d https://codeforces.com/contest/"$1"/problem/"$2"
}
Shell script:
Create the file mycommand with the following content in your $PATH and make it executable:
#!/bin/sh
oj d https://codeforces.com/contest/"$1"/problem/"$2"
$1 and $2 are positional parameters. If you call the script or function like $ mycommand 1348 A, $0 gets mapped to mycommand, $1 to 1348, $2 to A and so on. We put the double quotes around the variables in case they contain whitespace to prevent word splitting.
