watch command doesn't work for alias commands.
without alias
➜ scrcpy git:(master) git -P branch
* master
➜ scrcpy git:(master) watch git branch
with alias
➜ scrcpy git:(master) which gb
gb: aliased to git branch
➜ scrcpy git:(master) watch gb
Is it possible to add those effects in normal terminal? Modified terminal? Code something from 'scratch' for fun? Play sound every 3 seconds and lower the intensity of cursor highlight smoothly over 3 seconds time.
I was try to installing watchman on Ubuntu 19.10 but it throwing some issues.
My commands:
$ cd ~
$ git clone https://github.com/facebook/watchman.git
$ cd watchman/
$ git checkout v4.9.0
$ sudo apt-get install -y autoconf automake build-essential
python-dev
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install$ watchman --version
Issues:
scm/Mercurial.cpp: In constructor ‘watchman::Mercurial::infoCache::infoCache(std::string)’:

I want a variable to be incremented by 1 per second.
#!/bin/bash
var=0
watch -n 1 echo "$((var++))"
Output (after few seconds) :
Every 1.0s: echo 0
0
It didn't change on screen but when i enter echo "$var" output is 1.Why?
I have executed
>> watch tree ./
Now my problem is I'm unable to exit from watch - without closing the terminal.
I read man page of watch but they have not mentioned how to exit from watch screen.
Is there is magic key combo that you need to use to exit from watch ?
It's like one those problems you face when you for the first time open vim and don't know how to close it.
