How to merge two tables based on a matched column?
Hi,
Please excuse me , i have searched unix forum, i am unable to find what i expect ,
my query is , i have 2 files of same structure and having 1 similar field/column , i need to merge 2 tables/files based on the one matched field/column (that is field 1),
file 1:
file 2:
expected output (in file2 , excluding field1, need to merge rest of field with file1):
tried like this
but first column is also appearing.
Of course it is possible to use awk-scripts, sed-scripts, perl-scripts and probably another array of programmable text filters for this.
You might be interested to know that Unix offers a genuine tool for exactly your purpose: join. join takes two files as source and generates an output line (which format you can control) for each matching pair of lines.
Here is an example (taken from the join man page of AIX): suppose you have two files, "names" and "phone"
names:
phone:
The command
would produce the output:
Each line consists of the join field (per default the first field in the line, which is the last name) followed by the rest of the line found in the phone file, then the rest of the line in the names file.
There are options to control the process: display unmatched lines, declare different key values, separators, etc. Notice that join works on sorted files, therefore sorting one or both files before you use them influences output.

Hello,
I have a tab-delimited table that may contain 11,12 or 13 columns. Depending on the number of columns, I want to cut and get a sub table as shown below. However, the awk commands in the code seem to be an issue. What should I be doing differently?
