wCat is a clone of cat command available in bash but not in windows cmd. It is used to display or make a copy content of one or more files in the terminal
node wcat.js [options] [files]| Options | Working |
|---|---|
| -s | Converts Multiple Line Breaks into Single Line Breaks |
| -b | Adds Line Number to Non-empty Lines |
| -n | Adds Line Number to All the Lines |
-n and -b are 2 options which are mutually exclusive so if user types both of them together only the first enter option should work.
- node wcat.js filepath => displays content of the file in the terminal
- node wcat.js filepath1 filepath2 filepath3... => displays content of all files in the terminal(contactinated form) in the given order.
- node wcat.js -s filepath => convert big line breaks into a singular line break
- node wcat -n filepath => give numbering to all the lines
- node wcat -b filepath => give numbering to non-empty lines We can mix and match the options.
Edge cases:
- If file entered is not found then it gives file does not exist error.
Not Working So Far
- node wcat filenamepath > filename2path => put all the content of filename into filename2 by overriding and also creates filename2 if it doesn't exist.
- node wcat filename >> filename2 => append all the content of filename into filename2
- node wcat -s filename > filename2 =>get the file content of filename remove large spaces and save the output in filename2
