Top Forums Shell Programming and Scripting awk/sed column replace using column header - help Post 302206374 by jkl_jkl on Tuesday 17th of June 2008 02:11:57 PM

I feel I explained my query in a wrong way. Let me explain again:

Input file:

Code:
$ cat log.txt
Name Age Sex Lcation nfld alias xsd
CC 25 M XYZ asx KK Y
BB 21 F XAS awe SS N
SD 21 M AQW rty SD A

How can I replace the column with header "Lcation" with the column with header "alias" and delete the alias column?

Required output:

Code:
Name Age Sex alias nfld xsd
CC 25 M KK asx Y
BB 21 F SS awe N
SD 21 M SD rty A

I don't want to use field number because my actual file contains more than 70 fields and the field positions are not fixed(the above log.txt is just a sample). Thats why I am looking for a solution which replaces based on column header.

Please help.
