Be confused with cut

[goldenfire]

Freebsd1# echo "aaa.bbb" | cut -d'.' -f1,2
aaa.bbb

I think the result should be aaabbb.
Why there is still a '.'?
I am confused.
Could anyone help

cut(1):

     -f list
             The list specifies fields, separated in the input by the field
             delimiter character (see the -d option).  Output fields are [b]sepa‐
             rated by a single occurrence of the field delimiter character[/b].

Thanks a lot!
Does that mean I should use "awk" instead of "cut"?

It would appear in practice that cut(1) leaves the delimiter in the output. The example from the manpage ([cmd=c:\>] cut -d : -f 1,7 /etc/passwd[/cmd] leaves the ":"). As to what you should use, I don't know. sed(1)?

 

[crsd]

It depends on what you are trying to achieve. If you just need to delete '.', try using tr(1)

echo "aaa.bbb" | sed -e 's/\.//'

Or you can use 'tr' for that.
[CMD="> "]echo "aaa.bbb" | tr -d "."[/CMD]
