Hi...Can anyone please guide me on FIFO Pipes in UNIX.I have lerant things like creating fifo pipes,using them for reads and writes etc.I want to know what is the maximum amount of memory that such a pipe may have? Also can anyone guide me on where to get info on this topic from? (1 Reply)
Gurus,
I've a File Transaction Server, which communicates with other servers and performs some processing.It uses many Named PIPE's.
By mistake i copied a named PIPE into a text file.
I heard that PIPE files shouldn't be copied.Isn't it?
Since it's a production box, i'm afraid on... (2 Replies)
Hi!!
I have a problem reading from a fifo pipe in shell script.
The idea is simple, I have a C program with two pipe files:
An input pipe I use to send commands in shell script to the C program (echo "command" > input.pipe)
An output pipe that I read the result of the command also in... (4 Replies)
Hi
This is a exercise question from Unix network programming vol2.
Why the SIGPIPE signal is generated only for writers when readers disappear.
why not it is generated for readers when writer disappears.
I guess, if the writer didn't get any response like the reader gets EOF,
it will... (4 Replies)
Hi guys.
1. how much is the size of pipe?(i mean the buffer size)
2. is this size different in various UNIX derivations?
3. what happens if we write to a full pipe? does it block until get some free space(the other side receive data) or returns an error?
3. FIFO s are physical files on the... (2 Replies)
I'm trying to read a fifo using awk and comming across some problems. I'm writing to the fifo from multiple processes invoked by GNU Parallel:
mkfifo my_fifo
awk '{ a = a + $2 } END { for (i in a) print i, a }' my_fifo | sort -nk1 > sorted_output
grep -v '^@' massive_file | parallel... (3 Replies)
Hi All,
I'm creating a program which reads millions of bytes from the PIPE and do some processing. As the data is more, the idea is to read the pipe parallely.

See the code below:

awk '{print $1}' metadata.csv > nvpipe &

gensprep(8) ICU 50.1.2 Manual gensprep(8)NAME
gensprep - compile StringPrep data from files filtered by filterRFC3454.pl
SYNOPSIS
gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source ] [ -d, --destdir destination ]
DESCRIPTION
gensprep reads filtered RFC 3454 files and compiles their information into a binary form. The resulting file, <name>.icu, can then be read
directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library.
The files read by gensprep are described in the FILES section.
OPTIONS -h, -?, --help
Print help about usage and exit.
-v, --verbose
Display extra informative messages during execution.
-c, --copyright
Include a copyright notice into the binary data.
-s, --sourcedir source
Set the source directory to source. The default source directory is specified by the environment variable ICU_DATA.
-d, --destdir destination
Set the destination directory to destination. The default destination directory is specified by the environment variable ICU_DATA.
ENVIRONMENT
ICU_DATA Specifies the directory containing ICU data. Defaults to /usr/share/icu/50.1.2/. Some tools in ICU depend on the presence of the
trailing slash. It is thus important to make sure that it is present if ICU_DATA is set.
FILES
The following files are read by gensprep and are looked for in the source /misc for rfc3454_*.txt files and in source /unidata for Normal-
izationCorrections.txt.
rfc3453_A_1.txt Contains the list of unassigned codepoints in Unicode version 3.2.0....
rfc3454_B_1.txt Contains the list of code points that are commonly mapped to nothing....
rfc3454_B_2.txt Contains the list of mappings for casefolding of code points when Normalization form NFKC is specified....
rfc3454_C_X.txt Contains the list of code points that are prohibited for IDNA.
NormalizationCorrections.txt
Contains the list of code points whose normalization has changed since Unicode Version 3.2.0.
