Jan 23	comment	How could I make multiple symbolic links for multiple directories, conveniently @StephaneChazelas Oh right, I read too fast and completely missed the second part, sorry.
Jan 22	reviewed	Approve suggested edit on How can I open a file in VIM in readonly mode if it already has a swapfile?
Jan 18	comment	Why unix mv program doesn't need -R (recursive) option for directories but cp does need it? @RuslanKhusnullin Your coffee analogy works for `cp` and `mv` too - it does not require any level of "nerdness" to understand, just basic common sense. A true copy of a cup of coffee is not an empty cup - you have to recursively copy not only the cup, but all of its contents (the coffee) too. However, when you move a cup of coffee you don't have to move the contents separately - the contents move with the container naturally.
Jan 18	comment	Solaris: find the day of last Monday,Tuesday,…Sunday by means of shell script Don't worry, none of the other answers so far uses pure shell + Solaris `date` anyways.
Jan 18	comment	Changing tmux .bash_profile behavior It appears that tmux starts login shells by default. I am not sure if there is a reason for this, but if you want to make tmux start non-login shells instead you can add `set-option default-command bash` to your `.tmux.conf`. (`.bash_profile` is only read by login shells; non-login shells ignore it).
Jan 17	comment	What are the advantages of the Unix file system structure @fluffy Separate filesystems offer slightly stronger separation, but that point is partially moot as it is not possible to separate `/bin`, `/etc`, from `/`.
Jan 17	comment	Multiple similar entries in ssh config It appears the `%h` feature appeared in release 5.6 of OpenSSH. I was wondering why I hadn't seen it before - the version in Debian Squeeze is 5.5.
Jan 17	comment	Multiple similar entries in ssh config @user27915816 Yes, you are right, there is no way to do "templates" as far as I know. The best you can do is separate out the constant lines into a single `Host *` entry, and have a separate entry for each `Host XXX` that consists only of the parts that vary (i.e. the `Hostname XXX.YYY.ZZZ` line).
Jan 17	answered	Omitting extension with find?
Jan 17	comment	Recursive find that does not find hidden files or recurse into hidden dirs Where are you adding `-type f`? I'd put it between `-o` and `-print`.

Jan 16	comment	Multiline shell script comments - how does this work? That single-quote commenting method doesn't work on any section of script that itself uses single-quotes. And if you are using quotes anywhere near as much as you should, that means you'll have legitimate single quotes sprinkled all throughout the script. It is so much simpler to just use any decent editor that lets you do block linewise comments.

Dec 21	comment	Why is vi apparently broken (viminfo error E576), and how can I fix it? Is your `~/.viminfo` corrupt? Try moving it elsewhere and see if the problem returns. Keep in mind many systems that provide `vim` simply provide `vi` as a symlink to `vim`.
Dec 20	revised	Bash prompt not recognizing Unicode escapes added 217 characters in body
Dec 20	answered	Bash prompt not recognizing Unicode escapes
Dec 20	comment	Is there any way to test out PS1 Bash Prompts before committing them? A web tool sounds like even more of a pain than starting a new shell, unless you want to play around with `bash` when not on a Unix machine. Is that your goal (a web-based `bash`)?
Dec 20	comment	Is there any way to test out PS1 Bash Prompts before committing them? Define "commit". The easiest way for me is to just start a new shell. Then if I screw it up I can just exit it and no permanent changes have been made.
Dec 20	comment	how to add a description in footer As @ChrisDown has said, just go with a version control system. No need to reinvent existing, sophisticated wheels crudely (it takes a lot of time to implement an efficient and robust VCS).
