| awk | whitespace (one ore more spaces or tabs) for both input and output |
|
cat sampleinfo.txt | awk -F "\t" '{ print $1,$3 }' |
| join | one or more spaces | -t option | |
| perl | whitespace (one ore more spaces or tabs) when auto-splitting input with -a | -F'/<pattern>/' option | cat sampleinfo.txt | perl -F'/\t/' -ane 'print "$F[0]\t$F[2]\n";' |
