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.

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

colrm
COLRM(1) BSD General Commands Manual COLRM(1)NAME
colrm -- remove columns from a file
SYNOPSIS
colrm [start [stop]]
DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read
from the standard input. Output is written to the standard output.
If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec-
ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not
zero.
Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).
EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs.
SEE ALSO awk(1), column(1), cut(1), paste(1)HISTORY
The colrm command appeared in 3.0BSD.
