Simple AWK command

Simple AWK command

Simple AWK command

(OP)
Hello,

I've got following command - ls | awk 'FS= "." { print $2$1 }'
Result:
K900048.SMA
SMAK900051
SMAK900053
SMAK900055

why first line is not sorted to SMAK900048?

Best regards,
Damian

RE: Simple AWK command

Hi

Because you used FS="." as pattern. Reading and parsing the input line is performed before the regular pattern-action pairs are executed, so before your code sets the field separator.

Either set the field separator in the special BEGIN rule :

CODE

ls | awk 'BEGIN{FS="."}{ print $2$1 }' 
or use the interpreter's -F option to set the field separator :

CODE

ls | awk -F "." '{ print $2$1 }'
