merging
Hi all,


I have 2 files. I want to merge a portion or column in file 2 into file 1.

file 1 - not tab or space delimited

Code:
B_1       gihgjfhdj| hgfkddlldjljldjlddl
B_2       gihgjddshjgfhs| hgfkddlldjljldjlddl
B_3       gihgjfhdj| hgfkddlldjljldjlddlhgjdhdhjdhjhdjhdjhgdj


file2 - tab delimited

Code:
asdfg     1101    2579    +    492    229194403    0    -    be_10    -
D-asd     2669    4000    +    443    229194404    0    -    be_20    -
Perd    4162    5049    +    295    229194405    0    -    be_30    -

I need the output file where the 9th column or tab on file 2 is merged to file 1
output file (modified file1)

Code:
B_1       gihgjfhdj| hgfkddlldjljldjlddl  be_10
B_2       gihgjddshjgfhs| hgfkddlldjljldjlddl be_20
B_3       gihgjfhdj| hgfkddlldjljldjlddlhgjdhdhjdhjhdjhdjhgdj be_20

Please let me know the best way to do in unix or awk or sed.

In sh...
Code:
#!/bin/sh

cut -f9 f2 > tmpfile
paste f1 tmpfile

exit 0

f1 and f2 are respectively your first and second files

Hi,

or with awk:

Code:
awk 'NR==FNR{a[++i]=$9}NR!=FNR{t=$1;sub(/B_/,"",t);print $0 FS a[t]}' file2 file1

Output:
Code:
B_1       gihgjfhdj| hgfkddlldjljldjlddl be_10
B_2       gihgjddshjgfhs| hgfkddlldjljldjlddl be_20
B_3       gihgjfhdj| hgfkddlldjljldjlddlhgjdhdhjdhjhdjhdjhgdj be_30

Thanks Chris,
It worked for that particular files. I guess u were targeting /B_/. but I have many files that have different ids. So is there a way to make it a generalized code so that whatever the id is, the code works for any data with the same structure and format.

let me know.

Yupp,

try this:
Code:
awk '{getline s < "file2"; split(s,a,"[ \t]+");print $0 FS a[9]}' file1

For me it does work. So what exactly doesn't work for you.
