Hi neha_suri06,
If you want quick replies to your queries, and have those replies have a good chance of woking in your environment, it is crucial that you always tell us what operating system you're using, what shell you're using, and show us what you have tried.
Showing us the output from cat -v file gives us ambiguous data about what the actual contents are of the file named by file might be. If your sample input file has fields delimited by ASCII escape characters, we know that it contains at least two lines each containing somewhere between one and seven fields. To help us test code that might work to solve your problem, it is always better to include a copy of the data you want to process (in CODE tags) or upload a copy of the file itself. If there are questions about the data contained in a file, showing us the output from hexdump -C file (if it is available on your system) or od -bc file (which should be available on any UNIX or UNIX-like system) is always better than cat -v file because they both produce unambiguous output.
Refusing to answer questions about what you have tried and what you have considered trying makes it very clear that, despite what you said in your first post, this problem must not really be urgent for you.
Hi chandan.chaman and wisecracker,
As RudiC has already said, if you look closely at post #1 in this thread, you will see that the sample input show in that post is not the actual contents of the file named op.dat; it is the contents of op.dat after processing by cat -v. From that output, we don't know if there are any circumflex characters in op.dat, but we do know that if there are any, they are data rather than being field delimiters.
If we knew that there are no circumflex characters in the first field in op.dat (which is not stated anywhere in neha_suri06's requirements but might be assumed from the given example), one could try the grossly inefficient:
Code:
cat -v op.dat | awk -F'^' '{print $1}'
Much better solutions could be suggested if we knew what operating system and shell neha_suri06 is using and had a better understand of what neha_suri06 had already tried to solve this problem.

Hi,
Can anyone help:

Using awk or sed, I'd like to remove leading spaces after a comma and before a right justified number in field 6. Sounds simple but I can't find a solution. Each field's formatting must stay intact.
Input:
40,123456-02,160,05/24/2012,02/13/1977, 10699.15,0

cat
CAT(1) General Commands Manual CAT(1)NAME
cat - catenate and print
SYNOPSIS
cat [ -u ] [ -n ] [ -s ] [ -v ] file ...
DESCRIPTION
Cat reads each file in sequence and displays it on the standard output. Thus
cat file
displays the file on the standard output, and
cat file1 file2 >file3
concatenates the first two files and places the result on the third.
If no input file is given, or if the argument `-' is encountered, cat reads from the standard input file. Output is buffered in the block
size recommended by stat(2) unless the standard output is a terminal, when it is line buffered. The -u option makes the output completely
unbuffered.
The -n option displays the output lines preceded by lines numbers, numbered sequentially from 1. Specifying the -b option with the -n
option omits the line numbers from blank lines.
The -s option crushes out multiple adjacent empty lines so that the output is displayed single spaced.
The -v option displays non-printing characters so that they are visible. Control characters print like ^X for control-x; the delete char-
acter (octal 0177) prints as ^?. Non-ascii characters (with the high bit set) are printed as M- (for meta) followed by the character of
the low 7 bits. A -e option may be given with the -v option, which displays a `$' character at the end of each line. Specifying the -t
option with the -v option displays tab characters as ^I.
SEE ALSO cp(1), ex(1), more(1), pr(1), tail(1)BUGS
Beware of `cat a b >a' and `cat a b >b', which destroy the input files before reading them.
