I am using the bash shell.

When I view my recent command history using the "history" command from the prompt, it only shows me the commands starting at #928.

The commands I need are earlier...

This works like a charm, except that it takes a tab-delimited file and returns a space-delimited file. My fault for not mentioning it in the original post.

Greetings. I have a three column file, and there are some numbers in the second column that are <1. However I need all numbers to be positive, thus need to replace all those numbers with just one....

I need a quick way to change the format in a table of data

Here is an example of the input:
10 72 Value=177 VDB=0.0245 Value4=0,0,171,0...

You're 100% right. The long reason is that, just in the two days from when I posted and when I grabbed your code to use it, this aspect of the project changed and I was negligent in remembering the...

@Scrutinizer

Thank you very much. I think this is getting into the right ballpark. However,

for the input:

@wisecracker - thanks. The code works great, but doesn't get desiredthe results because there are line breaks.

@bartus11 - Input added!

I have large flat file from which I need to extract every case of a pairing of characters (GG)...

Thanks, worked like a charm

I have a flat file that looks like this, let's call it Chromosome_9.txt:
FT /Gene_Name="Guanyl-Acetylase 9"
FT /Gene_Number"36952"
FT ...

Perfect, this is just what i was looking for.

The data there was just an illustration, the actual files are lists of 1501 and 451 numbers respectively. The difference in number of lines is likely another issue.

The match must be 100% perfect...

Done, thanks!

Greetings.

I like to compare two lists of numbers, A.txt and B.txt, to see the numbers that are in B.txt but not in A.txt. I only need the "deletions" with reference to A.txt. Using the diff...
