I had to do something I could do in a way that worked fine, but I'm still wondering if there's a shorter way (which I think there is)...
I had to find only the ASCII files of a directory, and then work with them (that is, not only showing on screen)
What I did was
That worked pretty well, but I think it's kinda long for such an supposed-to-be-easy task.
So, could you help me finding another way to find only the ASCII files of a directory? If possible, not using sed or awk, since I still don't know these commands at all.
Hi Everybody!
Situation:
I have a large ASCII file (for example: 1-2 Mbytes) without linebreaks (\n).
Task:
I like inserting linebreaks after all 420 digits (byte).
(pattern: *\n*\n*\n...etc.)
My problem:
How? :-)
I like using shell script or (maybe) AWK (short) program.
Please,... (2 Replies)
We need to scramble data in a number of ASCII files. Some of these files are extremely large (1.2 GB). By scrambling, I mean that we need to substitute certain strings, which number around 400, with scrambled strings. An example has been given below
If "London" occurs in the file, then it... (2 Replies)
Dear Experts
I need to read a binary file. I know for example in byte number 3801-3804 there is a 4 byte number embeded. Is there a way to extract this number from this file and then convert it to ascii via unix??
Your help would be highly appreciated.
Very Best Regards

Hi,
I have a challenging task,in which i have to find the duplicate files by its name and size,then i need to take anyone of the file.Then i need to open the file and find for more than one pattern and count of that pattern.
Note:These are the samples of two files,but i can have more... (2 Replies)
When you are dealing with ASCII files it easy to check on line endings type. You can just use the file command. You are not always lucky enough to be dealing with ASCII files. So in the cases that you don't have ASCII files how can you check what type of line endings you have? Please list all... (5 Replies)

xargs
XARGS(1) General Commands Manual XARGS(1)NAME
xargs - construct argument list(s) and execute utility
SYNOPSIS
xargs [ -t ][[ -x ] -n number ][ -s size ][ utility [ arguments... ]]
DESCRIPTION
The xargs utility reads space, tab, newline and end-of-file delimited arguments from the standard input and executes the specified utility
with them as arguments.
The utility and any arguments specified on the command line are given to the utility upon each invocation, followed by some number of the
arguments read from standard input. The utility is repeatedly executed until standard input is exhausted.
Spaces, tabs and newlines may be embedded in arguments using single (`` ' '') or double (``"'') quotes or backslashes (``''). Single
quotes escape all non-single quote characters, excluding newlines, up to the matching single quote. Double quotes escape all non-double
quote characters, excluding newlines, up to the matching double quote. Any single character, including newlines, may be escaped by a back-
slash.
The options are as follows:
-n number Set the maximum number of arguments taken from standard input for each invocation of the utility. An invocation of utility will
use less than number standard input arguments if the number of bytes accumulated (see the s option) exceeds the specified size or
there are fewer than number arguments remaining for the last invocation of utility. The current default value for number is
5000.
-s size Set the maximum number of bytes for the command line length provided to utility. The sum of the length of the utility name and
the arguments passed to utility (including /dev/null terminators) will be less than or equal to this number. The current default
value for size is ARG_MAX - 2048.
-t Echo the command to be executed to standard error immediately before it is executed.
-x Force xargs to terminate immediately if a command line containing number arguments will not fit in the specified (or default)
command line length.
If no utility is specified, echo(1) is used.
Undefined behavior may occur if utility reads from the standard input.
The xargs utility exits immediately (without processing any further input) if a command line cannot be assembled, utility cannot be
invoked, an invocation of the utility is terminated by a signal or an invocation of the utility exits with a value of 255.
The xargs utility exits with a value of 0 if no error occurs. If utility cannot be invoked, xargs exits with a value of 127. If any other
error occurs, xargs exits with a value of 1.
SEE ALSO echo(1), find(1)STANDARDS
The xargs utility is expected to be IEEE Std 1003.2("POSIX") compliant.
