watchfile watches files in real time

Watchfile display given file. If there's any changes, rewrite it.

# screen will be cleard, and cat that file from (1,1)

install

homebrew

$ brew tap Cj-bc/watchfile
$ brew install watchfile

when you use hoembrew, it might not work and say 'Permission denied.' This is known big bug and this is caused because watchfile itself($(brew --prefix)/Cellar/watchfile//bin/watchfile) has no permission to execute. I'm not sure why it's occured, but the easy solution is to run: $ chmod 755 $(brew --prefix)/Cellar/watchfile/<version>/bin/watchfile

bpkg

$ bpkg install Cj-bc/watchfile -g

from source code

$ git clone https://github.com/Cj-bc/watchfile.git
$ cd watchfile
$ mv watchfile.sh /usr/local/bin/watchfile
