### Clarifications
> I don't understand tilde `~`, what is it and why is it used when restoring
programs?
Let's say you use `rails server` command often. You want `tmux-resurrect` to
save and restore it automatically. You might try adding `rails server` to the
list of programs that will be restored:
set -g @resurrect-processes '"rails server"' # will NOT work
Upon save, `rails server` command will actually be saved as this command:
`/Users/user/.rbenv/versions/2.0.0-p481/bin/ruby script/rails server`
(if you wanna see how is any command saved, check it yourself in
`~/.tmux/resurrect/last` file).
When programs are restored, the `rails server` command will NOT be restored
because it does not **strictly** match the long
`/Users/user/.rbenv/versions/2.0.0-p481/bin/ruby script/rails server` string.
The tilde `~` at the start of the string relaxes process name matching.
set -g @resurrect-processes '"~rails server"' # OK
The above option says: "restore full process if `rails server` string is found
ANYWHERE in the process name".
If you check long process string, there is in fact a `rails server` string at
the end, so now the process will be successfully restored.
> What is arrow `->` and why is is used?
(Please read the above clarification about tilde `~`).
Continuing with our `rails server` example, when the process is finally restored
correctly it might not look pretty as you'll see the whole
`/Users/user/.rbenv/versions/2.0.0-p481/bin/ruby script/rails server` string in
the command line.
Naturally, you'd rather want to see just `rails server` (what you initially
typed), but that information is now unfortunately lost.
To aid this, you can use arrow `->`:
set -g @resurrect-processes '"~rails server->rails server"' # OK
This option says: "when this process is restored use `rails server` as the
command name".
Full (long) process name is now ignored and you'll see just `rails server` in
the command line when the program is restored.
