awk - How to save each line in a text file as new file -

i have tab delimited text file 5 columns, , i'd each row own txt file contains information columns 2-5 , named after column 1.

for example, txt file has hundreds of rows similar this:

sample1name_oligos primer forwardseq reverseseq sample1name

sample2name_oligos primer forwardseq reverseseq sample2name

i'd have txt file named sample1name_oligos this:

primer forwardseq reverseseq sample1name

and txt file named sample1name_oligos looks this:

primer forwardseq reverseseq sample1name

i've tried 2 ways:

1. found thought solution:

awk '{print substr($0,match($0,$2)) >> ( $1 ".txt" )}' filename

(from http://www.linuxquestions.org/questions/linux-newbie-8/how-to-save-each-line-from-textfile-as-new-file-889795/)

this worked test file made (5 rows), when run on 100+ rows file first 17 files out , error:

awk: file18.txt makes many open files input record number 18, file myfile.txt source line number 1

i deleted row 18 , retried , got same error. deleted first 20 lines , retried , got same error.

2. same link, tried

cat myfile.txt | while read line; echo $line > "$line.txt"; done.

this made file each row looked this:

sample1name_oligos primer forwardseq reverseseq sample1name

and file named:

sample1name_oligos primer forwardseq reverseseq sample1name.

i'm not sure go here. i'd appreciate help. if it's not obvious, have little terminal experience i'd appreciate answers explain i'm missing.

awk -f'\t' '$1!=prev{close(out); out=$1".txt"; prev=$1} {sub(/[^\t]+\t/,""); print > out}' file
