Seperated by columns, merge in a file, sort them on common column
Hi All,

I have 4 files in below format. I took them as an example.

File 1: Cut from position 1-4 then 6-7 then 8-14 then rest left and make them as columns in one new file. Inserting character H to the initial of all line like HCTOT.
Code:
 
CTOT 456787897 Low fever
CTOR 556712345 High fever

File 2: Cut from position 1-4 then 6-7 then 8-14 then rest left and make them as columns in one new file. Inserting D as initial.
Code:
CTWE 456711111 Some Risk
CTWR 551124567 High Risk

File 3: Cut from position 1-4 then 6-7 then 8-14 then rest left and make them as columns in one new file. Insert L as initial.
Code:
CTRE 459754125 Doctor Required
CTEE 559754214 Home Sickness

File 4: Cut from position 1-4 then 6-7 then 8-14 then rest left and make them as columns in one new file.Insert M as initial.
Code:
CRRE 458757845 Hospital Required
CREE 558757812 Hospital Not required

Column 2 become common column in all 4 files.

Its easy to cut columns usind cut -c command and insertion using sed command but not get the desired output while merge them as columns. I used paste command for that but while pasting I see one blank column in between two columns like CTOT<space><space>45.

I would see my output as:
Code:
HCTOT 45 6787897 Low fever
DCTWE 45 6711111 Some Risk
LCTRE 45 9754125 Doctor Required
MCRRE 45 8757845 Hospital Required
HCTOR 55 6712345 High fever
DCTWR 55 1124567 High Risk
LCTEE 55 9754214 Home Sickness
MCREE 55 8757812 Hospital Not required

I used sorting after that and combined all my logic into a shell script but I didn't get the desired output. Please help me out.
Thank you.

LEARN ABOUT LINUX

column

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME

     column -- columnate lists

SYNOPSIS

     column [-ntx] [-c columns] [-s sep] [file ...]

DESCRIPTION

     The column utility formats its input into multiple columns.  Rows are filled before columns.  Input is taken from file operands, or, by
     default, from the standard input.	Empty lines are ignored.

     The options are as follows:

     -c      Output is formatted for a display columns wide.

     -s      Specify a set of characters to be used to delimit columns for the -t option.

     -t      Determine the number of columns the input contains and create a table.  Columns are delimited with whitespace, by default, or with
	     the characters supplied using the -s option.  Useful for pretty-printing displays.

     -x      Fill columns before filling rows.

     -n      By default, the column command will merge multiple adjacent delimiters into a single delimiter when using the -t option; this option
	     disables that behavior. This option is a Debian GNU/Linux extension.

ENVIRONMENT

     The COLUMNS, LANG, LC_ALL and LC_CTYPE environment variables affect the execution of column as described in environ(7).

EXIT STATUS

     The column utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

	   (printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; 
	   printf "HH:MM/YEAR NAME
" ; 
	   ls -l | sed 1d) | column -t

SEE ALSO

     colrm(1), ls(1), paste(1), sort(1)

HISTORY

     The column command appeared in 4.3BSD-Reno.

BUGS

     Input lines are limited to LINE_MAX (2048) bytes in length.
