Hi @Scrutinizer.. issue is, in output file each line has to start with string containing 9K like below .

Code:
GL_0BC_901_1AG_A_CASR9KTR176,BGL_KMR_919_1AC_B_CASR920R899
BGL_0BC_901_1AG_A_CASR9KTR176,BGL_CHT_903_1AC_B_CASR920R879,BGL_BAM_912_2AC_B_CASR920R879,BGL_BAM_912_1AC_B_CASR920R879,BGL_BAM_907_1AC_B_CASR920R879

For example, consider below sample input file :

Need to grep row whose string contains 9K in column 1 and then grep its corresponding row in column 2. Suppose check for 9K1 then grep A1, check for A1 in column 1 if not, output result as shown in below expected output file
Then again check for 9K1, grep A2, look for A2 in column1, if found grep its corresponding row value B2.
Now check for B2 value in column 1, then grep for C2 instead of A2 as we have already considered previously in lookup. Now look for C2 in column and grep D2 instead of B2.
This needs to be checked for all rows in column 1 that contains 9K, as there can be rows with value 9K2, 9K3, 9K4 in column 1 with corresponding data in column2.

Sample Input File :
Code:
9K1,A1
9K1,A2
9K1,A3
9K1,A4 
9K1,A5 
A2,B2
B2,A2
B2,C2
C2,B2
C2,D2
A5,B5
B5,C5
B5,A5
9K1,A6
A6,B6
B6,A6
B6,C6

Output required :

Code:
9K1,A1
9K1,A2,B2,C2,D2
9K1,A3
9K1,A4
9K1,A5,B5,C5
9K1,A6,B6,C6

But below is output returned by code.(which is not as expected output required)

Code:
9K1,A3
9K1,A4
9K1,A5
9K1,A6,B6,C6

zegrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
