Problem in extraction when space is a field delimiter
I have more than 1000 files to parse. Each file contains few lines (number of lines varies) followed by a header line having all column's name (SPOT, NAME etc) and then values for those columns.
**Example File:
. . . . . .
. . . . . .
Problems:
1) I need to remove all lines before the header line (for each file).
2) I need to extract 2 columns, let say 2nd (NAME) & 5th column (CHDN_MED). Since there is no values for 2nd & 4th rows for 5th column, it should give a blank space for each in output file. But its giving 6.3 and 6.7 respectively from the 6th column (I am tring with AWK).
The desired output file is :
**the actual files are with .xls extension and each file has more than 50 columns and 9,000 rows.
Please advise
Thanks

Hello,
Is there a direct command to check if the delimiter in your file is a tab or a space? And how can they be converted from one to another.
Thanks,

column
COLUMN(1) BSD General Commands Manual COLUMN(1)NAME
column -- columnate lists
SYNOPSIS
column [-tx] [-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.
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.
