Get the last 4 characters of output from standard out
How about tail
, with the -c
switch. For example, to get the last 4 characters of "hello":
echo "hello" | tail -c 5
ello
Note that I used 5 (4+1) because a newline character is added by echo
. As suggested by Brad Koch below, use echo -n
to prevent the newline character from being added.
Using sed
:
lspci -s 0a.00.1 | sed 's/^.*\(.\{4\}\)$/\1/'
Output:
4dc9
Do you really want the last four characters? It looks like you want the last "word" on the line:
awk '{ print $NF }'
This will work if the ID is 3 characters, or 5, as well.
