I have checked with printf and tried everything but still the output is not as i am expecting but it 90% correct
in attached screen shot if you will see it is adding tab before printing both the output but not in next line. it is showing two type of put put line 1 & 4 is one way rest all line is another way. there is something wrong with TAB but not able to find what.
Hi,
I work with AIX 5 and have two basic questions:
1) How do I underline/bold a word in a text output? Any way to do it with echo command?
basic example: echo "FOLDER " >> folder.txt ( I wish the word FOLDER to be underlined and bold).
2) Suppose I have the following pipe delimited... (1 Reply)
Hi,
I am confused about the output of find command.
Please see the two find commands below.
When i put "*.c" i get lots of files. But when i put *c only i get only one file.
Any answer??

when I do the find command from / , there are a lot of directories that I do not have access to and so I get
"find: cannot open ..."
How can I suppress these messages so only what was found is output.
I was thinking on
find / -name 'searchterm' | grep -v find
but this doesnt work

I'm trying to "paste" two files but the result is not aligned.
File1 looks like this:

File2 looks like this:

Then I run a paste command:
paste File1 File2 > result.cnt
Then result.cnt file is created like this:... (4 Replies)

Hi guys -
I am trying a small script to tell me if there is a file that exists less than 1k. It should report ERROR, otherwise the check is good.
I wrote this script down, however it never runs in the if/then statement. It always returns the echo ERROR.

Hello All,
I am new to this shell scripting , I wanted to modify the output of my find command such that it does not display the path but only file names , for example I am searching for the files which are modified in the last 24 hours which is

Hi,
I'd like to assign the output of the find command to a variable.
What I need is to run the find command, and if it returns zero files, the program exits.
so i'm trying to assign the output of the find command to the $var1 variable....and then if this is less than one, I echo a... (2 Replies)
Hi All,
I am trying to run find command in a script to list out certain files based on a patter. However, when there is no file in the output, the script should exit.
Tried a couple of operators (-n, -z) etc but the script does not work.
I am confused whether a null string is returned... (3 Replies)

stdio
STDIO(3S)STDIO(3S)NAME
stdio - standard buffered input/output package
SYNOPSIS
#include <stdio.h>
FILE *stdin;
FILE *stdout;
FILE *stderr;
DESCRIPTION
The functions described in section 3S constitute a user-level buffering scheme. The in-line macros getc and putc(3S) handle characters
quickly. The higher level routines gets, fgets, scanf, fscanf, fread, puts, fputs, printf, fprintf, fwrite all use getc and putc; they can
be freely intermixed.
A file with associated buffering is called a stream, and is declared to be a pointer to a defined type FILE. Fopen(3S) creates certain
descriptive data for a stream and returns a pointer to designate the stream in all further transactions. There are three normally open
streams with constant pointers declared in the include file and associated with the standard open files:
stdin standard input file
stdout standard output file
stderr standard error file
A constant `pointer' NULL(0) designates no stream at all.
An integer constant EOF (-1) is returned upon end of file or error by integer functions that deal with streams.
Any routine that uses the standard input/output package must include the header file <stdio.h> of pertinent macro definitions. The func-
tions and constants mentioned in sections labeled 3S are declared in the include file and need no further declaration. The constants, and
the following `functions' are implemented as macros; redeclaration of these names is perilous: getc, getchar, putc, putchar, feof, ferror,
fileno.
SEE ALSO open(2), close(2), read(2), write(2), fread(3S), fseek(3S), f*(3S)
DIAGNOSTICS
The value EOF is returned uniformly to indicate that a FILE pointer has not been initialized with fopen, input (output) has been attempted
on an output (input) stream, or a FILE pointer designates corrupt or otherwise unintelligible FILE data.
For purposes of efficiency, this implementation of the standard library has been changed to line buffer output to a terminal by default and
attempts to do this transparently by flushing the output whenever a read(2) from the standard input is necessary. This is almost always
transparent, but may cause confusion or malfunctioning of programs which use standard i/o routines but use read(2) themselves to read from
the standard input.
In cases where a large amount of computation is done after printing part of a line on an output terminal, it is necessary to fflush(3S) the
standard output before going off and computing so that the output will appear.
BUGS
The standard buffered functions do not interact well with certain other library and system functions, especially vfork and abort.
