Hi All,
..................................
Also on a follow up if I want to replace 008 to 009 . 008 is on the same column 33-35. What should I do
Hello arunkumar_mca,
Position of a character(s) is different from column number.
Example:
In above example if you talk in normal terms then position of a is 7 and it is NOT 7th column in that line.
Now question is when it becomes 7th column, let us think by default field separator is SPACE(I am talking about awk here). So your 7th position will be "called as " 7th field/column when field delimiter of awk is been set to NULL. Which is again a GNU awk function only. So please clear in your statements here.
Thanks,
R. Singh

From googling and reading man pages I figured out this sorts the first column by numeric values.
sort -g -k 1,1
Why does the -n option not work? The man pages were a bit confusing.
And what if I want to sort the second column numerically? I haven't been able to figure that out. The file... (7 Replies)

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.
