Save Separate Columns Into Separate Files using Awk
Assume that you have a column of data and you want to separate each column into it's own file.
It's relatively easy in awk.
Input is a sha256 or hash of ebooks:
1~$ sha256sum *.pdf
29scac1ae26617a210e2211cce308aa2b770b08cb51f46621b13be272877cc068 ebook1.pdf
3edbd3d4419878ee9ab68b211fc69e145eb776309273ab467e2f1bdc912d0252a ebook2.pdf
and script is as follows:
1~$ sha256sum *.pdf|awk '{
2 for(i=1;i<=NF;i++) print $i > ("temp_hash" i)
3 }'
It produces two file outputs (since we only have two columns.
temp_hash1 - containing the first column (or the hash
1~$ cat temp_hash1

3edbd3d4419878ee9ab68b211fc69e145eb776309273ab467e2f1bdc912d0252a
temp_hash2 - containing the filename
1~$ cat temp_hash2
2ebook1.pdf
3ebook2.pdf
