Hi Tobias, Based on what you scrieb:
> mkfifo xyz > tee my.log <xyz & > ls -la >xyz 2>&1 > rm xyz > mkfifo creates a 'named pipe' > tee is running in the background as long as the xyz exists > ls writes stdin + stderr to the pipefile, and my failing OP attempt, ls -R .../linux-3.3.6 | tee >(grep -m 5 devices > temp.txt) could you please put together a command _your way_ (for me to try) that _completely_ and _successfully_ does what I had wanted to achieve: 1. To see the 'ls' output scroll on the console all the way to the bitter end (as if it was all alone without the pipe: ls -R linux-3.3.6 ) no matter when 'grep' decided to exit and 2. At the end of the full 'ls' listing to find in the 'temp.txt' file just five lines corresponding to the first five lines in the 'ls' output containing the word "devices". NOTES 1. Instead of 'linux-3.3.6' (and -R), you can _obviously_ use any directory with plenty of files to generate, say, 10 seconds worth of display. 2. The "devices" word can be _obviously_ any word of _your_ preference, as long it is guaranteed to appear in the 'ls' output on at least five lines. For example, Donaudampfschifffahrtsgesellschaftskapitän will do (if it happens to occur on at least five lines in the 'ls' output). 3. The "5" in 'grep -m 5' can be as low as "1". Not too large, though, so as not to wipe out a typical Linux user drive size of 500KB in the process. (while at it, assume a CPU at least the power of 386SX) Hochachtungsvoll, -- Alex PS I remember reading somewhere that a construct like >( grep ...) creates a so-called 'named pipe'. Go figure. -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
