Does anyone know how I could to add a column of numbers (1s, or 2s, or..., or 6s) to two-column text files (tab-delimited), where the specific number to be added varies as a function of the file naming?
Currently, each of my text files has two columns, so the column with the repeated number in it would be the third column. The groups of six text files are located within separate directories, and the easiest way to get at their naming (which determines which number should be added) is by using "ls" - it will always list them in the right order, such that first text file listed should have a third column added with "1s" (for as many rows as it has; where the number of rows varies depending on the specific text file); and the second text file listed should have a third column appended with "2s", so on and so forth.
You don't need ls for that; in fact, it's usually the wrong way to do it. Use filename expansion instead.
Quote:
I am still quite new to programming, and my intuition tells me I should use the command "ls" and then pipe "|" that to a certain command that would execute "if the file is the first one, add a column of ones, if file is the second one, a column of twos..." etc.
No, loop through the files with filename expansion.
The awk script might have to be tweaked, depending on the exact format of the files.

I have a tab delimited text file where the first column can take on three different values : 100, 150, 250. I want to extract all the rows where the first column is 100 and put them into a separate text file and so on. This is what my text file looks like now:

compile_et
COMPILE_ET(1) General Commands Manual COMPILE_ET(1)NAME
compile_et - error table compiler
SYNOPSIS
compile_et file
DESCRIPTION
Compile_et converts a table listing error-code names and associated messages into a C source file suitable for use with the com_err(3)
library.
The source file name must end with a suffix of ``.et''; the file consists of a declaration supplying the name (up to four characters long)
of the error-code table:
error_table name
followed by up to 256 entries of the form:
error_code name, " string "
and a final
end
to indicate the end of the table.
The name of the table is used to construct the name of a subroutine initialize_XXXX_error_table which must be called in order for the
com_err library to recognize the error table.
The various error codes defined are assigned sequentially increasing numbers (starting with a large number computed as a hash function of
the name of the table); thus for compatibility it is suggested that new codes be added only to the end of an existing table, and that no
codes be removed from tables.
The names defined in the table are placed into a C header file with preprocessor directives defining them as integer constants of up to 32
bits in magnitude.
A C source file is also generated which should be compiled and linked with the object files which reference these error codes; it contains
the text of the messages and the initialization subroutine. Both C files have names derived from that of the original source file, with
the ``.et'' suffix replaced by ``.c'' and ``.h''.
A ``#'' in the source file is treated as a comment character, and all remaining text to the end of the source line will be ignored.
BUGS
Since the original compile_et uses a very simple parser based on yacc(1), and this current version of compile_et uses an awk/sed combina-
tion of scripts, its error recovery leaves much to be desired.
