Grep Write Error No Space Left On Device
Anybody can answer The best answers are voted up and rise to the top How can I fix a Broken Pipe error? up vote 17 down vote favorite 5 I recently reinstalled RVM (following the instructions at http://rvm.io) after a fresh install of Ubuntu 12.10 when I got an SSD Drive. Now, when I type: type rvm | head -1 I receive the following broken pipe error in linux error: rvm is a function -bash: type: write error: Broken pipe But if I immediately repeat the command then I only receive: rvm is a function And it appears everything is ok? What's happening? What can I do to fix it? It doesn't happen always. It appears to be more sporadic. I've tried to find some kind of pattern to it but haven't yet. bash ruby .bash-profile rvm share|improve this question edited Feb 20 '13 at 16:44 terdon 33.5k66299 asked Feb 20 '13 at 15:29 Jason Shultz 2352410 add a comment| 3 Answers 3 active oldest votes up vote 27 down vote accepted Seeing "Broken pipe" in this situation is rare, but normal. When you run type rvm | head -1, bash executes type rvm in one process, head -1 in another.1 The stdout of type is connected to the "write" end of a pipe, the stdin of head to the "read" end. Both processes run at the same time. The head -1 process reads data from stdin (usually in chunks of 8 kB), prints out a single line (according to the -1 option), and exits, causing the "read" en

So, I do: SubdirsArray=(`find ./I_am_a_dir_with_many_subdirs/ -maxdepth 2 -mindepth 2 -type d | sort`) Executing the script, I get the following error messages: sort: write failed: standard output: http://superuser.com/questions/728897/is-there-a-way-around-broken-pipe Broken pipe sort: write error As explained in this post: probably sort executes and closes the pipe, before find completes writing to it. Thus write() command initiated by find gets an error EPIPE "Broken pipe", OS sends find a SIGPIPE. Before the SIGPIPE reaches find, it prints the error message, then gets SIGPIPE and dies. Questions: So, what does my SubdirsArray contain? The Subdirs, that find found, but sort left unsorted? If so, than what would be the way around this issue with broken pipes? Make find write it's results to a temporary file and then make sort read it? I don't understand, why "it's also nothing to be concerned about" if it happens within a non-interactive shell: why? My SubdirsArray contains something unsorted and further in the script, I assume, that its elements are sorted?! I get two error messages: sort: write failed: standard output: Broken pipe sort: write error In this thread it is suggested, that sort doesn't have enough space in a temporary directory to sort all the input. But, doesn't it mean, that sort got something from find?!? I'm confused... Anyways, I tried to use SubdirsArray=(`find ./I_am_a_dir_with_many_subdirs/ -maxdepth 2 -mindepth 2 -type d | sort -T /home/temp_dir`) but it didn't help. P.S. I'm not sure whether it's i

I want to try the unix pipe, the command is like this: echo new | find . the standard output of the echo should be "new", then I guess find command will use this output as input to find the file named "new". But the output is all the file names in my current dir, the last line is "echo: write error: Broken pipe". Can anyone kindly tell me why this is happening? Thanks.

That's why you got the error. Code: find . -name new assuming that new is real file name you expect to find. There is no "new" predicate for the find command. How about this Code: ls | grep 'a' This finds all the files with the letter a in the filename in the current directory.
