Top Forums Shell Programming and Scripting awk to print fields that match using conditions and a default value for non-matching in two files Post 302994137 by cmccabe on Sunday 19th of March 2017 05:08:33 PM

I made a typo in on of the file1 lines, BCRA1 should be BCRA2.

file1
Code:
BRCA2
BCR
SCN1A
fbn1

current output:
Code:
awk 'BEGIN{FS=OFS="\t"}
{$0=toupper($0)}
FNR==NR{
   if(NR>1 && ($7 ~ "FULL GENE SEQUENC")) {
          gsub(" ","",$5)       #removing white space
          n=split($5,v,"/")
          d[v[1]] = $4          #from split, first element as key
      }
      next
}{print $1, ($1 in d?d[$1]:279)}' file2 file1
BRCA2    279
BCR    279
SCN1A    279
FBN1    85

FULL GENE SEQUENC could also be case in sensitive so I added a check in for that... why isn't FULL GENE SEQUENCE used, when I try that I get all the names with a value of 279.

Code:
awk 'BEGIN{FS=OFS="\t"}
{$0=toupper($0)} {$7=toupper($7)}
FNR==NR{
   if(NR>1 && ($7 ~ "FULL GENE SEQUENC")) {
          gsub(" ","",$5)       #removing white space
          n=split($5,v,"/")
          d[v[1]] = $4          #from split, first element as key
      }
      next
}{print $1, ($1 in d?d[$1]:279)}' file2 file1
BRCA2    279 
BCR    279
SCN1A    279
FBN1    85

desired output
Code:
BRCA2    81   - match in line 2 of $5 in file 2, BRCA 1, BRCA2
BCR    279     - match in line 2 of $5 in file but $7 is not full gene sequence
SCN1A    279
fbn1    85

Thank you Smilie.

NAME
merge - three-way file merge SYNOPSIS
file1 file2 file3 DESCRIPTION
combines two files that are revisions of a single original file. The original file is file2, and the revised files are file1 and file3. identifies all changes that lead from file2 to file3 and from file2 to file1, then deposits the merged text into file1. If the option is used, the result goes to standard output instead of file1. An overlap occurs if both file1 and file3 have changes in the same place. prints how many overlaps occurred, and includes both alterna- tives in the result. The alternatives are delimited as follows: lines in file1 lines in file3 If there are overlaps, edit the result in file1 and delete one of the alternatives. This command is particularly useful for revision control, especially if file1 and file3 are the ends of two branches that have file2 as a common ancestor. EXAMPLES
A typical use for is as follows: 1. To merge an RCS branch into the trunk, first check out the three different versions from RCS (see co(1)) and rename them for their revision numbers: 5.2, 5.11, and 5.2.3.3. File 5.2.3.3 is the end of an RCS branch that split off the trunk at file 5.2. 2. For this example, assume file 5.11 is the latest version on the trunk, and is also a revision of the "original" file, 5.2. Merge the branch into the trunk with the command: 3. File 5.11 now contains all changes made on the branch and the trunk, and has markings in the file to show all overlapping changes. 4. Edit file 5.11 to correct the overlaps, then use the command to check the file back in (see ci(1)). WARNINGS
