Unfortunately, I'm getting the same error that there is no file specified as argument2....

Hi,

I did not alter your script, just copy pasted it into a shell and run it. When the shell produced an error of /bin/ksh: bad interpreter: No such file or directory, I deleted the first line of...

I'm sorry my explanations were not clear.

The executable command takes the columns of file specified in argument 1 (infile1) and adds them to the file specified in argument 2 (infile2). It creates...

Hi,

The syntax for the combining.executable is correct and it would not put the data from infile3 in front of the infile2 in outfile2. The excitable will add columns from infile3 to the end of...

Each of the files consisted of 7 columns: the first three columns are the same in each file and the other 4 columns are the actual data (but we need to use only the last three of those). The merging...

I've got a directory of about 6000 txt files that look like this:

I need to execute a command on them to combine them and, in the end, have one big file with...

Thank you guys!
It works!

I'm not sure what you mean. Do you suggest to write out $3 to $8 instead of the loop?
The thing is that this is an example. In reality, the file had over 200K columns and I need the loop (or...

It is quite ambitious indeed, but I need 1 million columns (it is for the genetic analysis).

The output,...
