Could you please try following and let me know if this helps.
Thanks,

Hi Ravinder,
Note that setting the 4th field to a backspace character does not remove the 4th field. Note also that if any of the fields contain spaces between words within the field, you need to set FS to tab as well as setting OFS to tab to get the proper output. For example, the command:
produces the output:
My interpretation of the request to "remove the column 3 and column 4 and insert a word in column 3" is different than yours. I thought it meant to delete fields 3 and 4 and modify the new 3rd field. You thought it meant to replace field 3 and delete field 4. And the code provided by the OP, added text to the end of the 2nd field, deleted the 3rd and 4th fields, and added a new empty field to the end of each line.
Until we get an unambiguous description of the desired processing, I don't know which interpretation is correct.

Hi
I have a txt file with 4 columns where I need to add 4 empty columns in the middle meaning that I need what is currently column 4 to be column 8 in a new file.
The idea is that I have to use the file as input in a program that reads the data in column 1 and 8, so the content of the other... (8 Replies)
I have a large text-file with tab-delimited genetic data that looks like:
KSC112 KSC234 0 0 1 1 A G C T
I simply wan to delete the first column, but since the file has 600 000 columns, it is not possible with awk (seems to be limited at 32k columns).
Does anyone have an idea how to do this? (2 Replies)

Hello,

Hello,
I have some tab delimited files that may contain blank columns. I would like to delete the blank columns if they exist. There is no clear pattern for when a blank occurs.
I was thinking of using sed to replace instances of double tab with blank,
sed 's/\t\t//g'
All of the examples... (2 Replies)
