Creating a shortcut
Hi, I want to match a column of one file with many others and take the average of each one and put them into one file (I know sounds complicated).

so the 1st file is just a list of names that I want to match with the 2nd file that have names along with rows of values.

Code:
awk 'NR==FNR{a[$1];next}($1 in a){print}' 1st.txt 2nd.txt

However I also want to match the 1st file with file 3,4,5,6 etc. How can I write a code (or modify it to do that). Basically 1st file matching with 2md, 3rd, 4th etc...

After I get the match in a output file for files 2,3,4,5 etc., I want to then average it using this code

Code:
awk '{ M=NF; for(N=4; N<=NF; N++) T[N]+=$N } END {printf("%f", T[4]/NR);for(N=5; N<=M; N++) printf("\t%f", T[N]/NR);printf("\n");}'

Again I want to do it simultaneously for all files at once. After I want all the values along with the name of the initial files (2,3,4,5 etc) into one final output file along with the values.

Hope I did not confuse anyone..

I am currently dong this one by one and it is taking forever... I just want one file i the end with everything (along with names for each row).

Thanks

keyhead

keyhead(1)						      General Commands Manual							keyhead(1)

Name
       keyhead - Change FITS or IRAF header keyword names

Synopsis
       keyhead [-hknv] <FITS or IRAF file> kw1=kw1a kw2=kwd2a ... kwn=kwdna

Description
       Change the names of keywords in FITS or IRAF image headers.  Each current image keyword whose entry is to be modified should be followed by
       an equal sign and a second keyword, with no intervening spaces.	If the -r option is used, the value of the second keyword is transfered to
       that  of the first. Otherwise, the name of the first keyword is changed to the second keyword.  To change keywords in a list of files, sub-
       stitute @<listfile> for the file names on the command line.  To change a lot of keywords, put them, one pair separated by an = sign with no
       spaces  per  line, in a file and substitute @<keylistfile> on the command line.	If two @ commands are present, the program will figure out
       which contains file names and which contains keywords.  Lines in a keyword list file which do not contain an = are ignored.

Options
       -h     Write HISTORY line into output header with sethead version, current date and time, and names of keywords set.

       -k     Write KEYHEAD keyword into output header with the keyhead version, current date and time, and names  of  keywords  whose	names  are
	      changed.	If a KEYHEAD keyword already exists, move the old value to a HISTORY line before writing the new value

       -n     Write a new file with an added "e" before the extension.

       -r letter
	      Replace  value of 1st keyword with value of 2nd keyword instead of changing the name of the 1st keyword to the 2nd keyword.  The 2nd
	      keyword remains in the header.  If the 1st keyword does not exist in the header, it is created.

       -v     Print confirmations of each keyword change.
