Transforming an n-column file to a single-column file

I have a file like this

chr1:752426-753176_NR_015368_LOC643837 chr1:752515-753265_NR_024321_NCRNA00115

Where separation is with a tab, it has n number of columns and n number of rows.

What I want to do is to have one single column of my whole data. like this 

chr1:752426-753176_NR_015368_LOC643837 
chr1:752515-753265_NR_024321_NCRNA00115

Is there any one-liner in shell or Perl that can help me achieve this?

Thank you in advance.

Yes, it is possible.

  • Use the -a flag to split @F on columns
  • print or say each element of @F

  • Use > to redirect output to a new file or use the -i flag to enable in-place editing. 

    $ perl -anE 'say for @F' input.txt > output.txt

You can try doing:

sed -i.bak 's/\t/\n/g' file
