awk FS=: '{print $1}' instead of cut -d: -f1
awk FS="<" '{print $2}' instead of cut -d'<' -f2
awk FS=">" '{print $1}' instead of cut -d'>' -f1echo test,123 | awk -F, '{print $1}'
awk 'BEGIN {FS=":"};{print $1}'
$ echo 'Sample123string42with777numbers' | awk -F'[0-9]+' '{print $2}'
string awk -v FS="\t"EXAMPLES Print and sort the login names of all users:
BEGIN { FS = ":" }
{ print $1 | "sort" }
There is nothing wrong with using FS instead of -F.
FS is not used on the command line and doing so is asking for trouble. FS is a built-in variable and as such is treated specially.
