Row to column converter using Awk or grep?
Hello,

Can someone please help me on this.Smilie
I have a file which has more than 1 million lines (XML file).

What I need is:

Search for "abcd" in the input file > output the result into a output.txt (colloum1)

Search for "efghi" in the input file > output the result in to a output.txt (coluun2)

Search for "zzzz" in the input file > output the result in to a output.txt (coluun3)

Thanks in advance

What defines a "column". Is the output to be in XML as well? Anyway, see "info paste" (since the man page might be a bit deficient). Essentially:
Code:
grep abcd file1 >output1.txt
grep efghi file1 >output2.txt
grep zzzz file1 >output3.txt
paste output[123].txt >output.txt
rm output[123].txt

Can you grep on each of the three inputs to temp files, called temp1 temp2 temp3
And then use the paste command to put them into columns
Code:
paste temp1 temp2 temp3 >finalfile
