Agreed, Rob Pike, in his search engine example at Google's I/O 2012 IIRC, made the explicit point that mutexes are there and that channels are for joining large concurrent parts of the program together; guarding a data structure seems too s

I realise the point is to show sometimes vim is inappropriate. However, the commands given in the first one are long-winded and not equivalent, I'm not sure the readers who stand to gain from the article will notice this. As I wrote elsewhe

Further to my reply to sibling-reply finnw, here's the pattern of digits, further showing his 10 * 9, etc., breakdown. $ pins | > sed -r ' > :a; s/^([0-9])(.*)\1/\1\2a/; ta; s/[0-9]/a/ > :b; s/a([0-9])(

Right, and about a quarter contain the same digit at least twice in a row, which may be the "double digit" the grandparent referred to. $ pins() { seq -f '%04.0f' 0 9999; } $ pins | egrep -c '(.)\1' 2710 $ pins | egrep -c

How good is the platform detection accuracy? I ask because for goo.gl I see analytics with the + suffix plump for many "Other Unix" when the majority of those would have been Linux.

Disappointed to see no mention of GNU Stow there, very handy for /usr/local having multiple version of foo installed and being able to make one of them current, e.g. rewind if a new one breaks things. http://www.gnu.org/software/stow/

It's read as "cmd, stdout to file, stderr to the same place as stdout".

zsh had the idea first IIRC.

No, I meant the window's furniture so no colours. I agree, a tty-wrapper, like tmux, would provide another option. I don't suppose there are terminals generally about where `tput hs' is true. Have you considered using the end of the prompt

I too prefer just PS1='$ ', I want the cursor to be the same distance from the margin every time, to have maximum length for typing without wrapping, and the ability to put in a few separator lines between command output by just tapping Ret

Nice to see tr getting some use, though given the sed on either side I wonder if sed -r 's/\<./\U&/g; s/ +//g; s/[^a-zA-Z].*//' would be better. Note, the last s/// doesn't need a g.

Thanks, I think you've corrected me on this before and I haven't learned! My Plan 9 comes from before this switch.

To withdraw shell programming from Unix takes away one of its strengths. Not everything warrants Python, etc.

Removing files is a common need coupled with find yet many readers don't know of -delete; I was pointing it out. That doesn't weaken xargs's valid uses. You seem a little defensive? :-)

What's wrong with cat -- * >../foo given that cat(1posix) does support --.

Backticks, ``, and $(), use IFS to parse the command's output into words which then become the $()'s replacement and IFS normally contains \n.

You wouldn't like Plan 9 then; it wisely took the decision to forbid spaces (U+20) in file names at the kernel level.

It's most definitely catenate. I understand catenate to mean chain and concatenate to be to chain together. Since "cat foo bar xyzzy" doesn't modify the files to join them in any way I don't think they're chained together. Besides, ken &#38

The difference between cat file | foo foo <file assuming foo only reads stdin so `foo file' isn't possible, is that with the latter the shell will open file for reading on file descriptor 0 (stdin) before execing foo and th

With < on a FIFO it's the shell that blocks on opening before the command, e.g. cat, is run.
