From 6dcd6d0152200794a26b52ff762a110268551ba6 Mon Sep 17 00:00:00 2001 From: Tiezhu Yang Date: Sat, 19 Nov 2022 10:55:04 +0800 Subject: samples: pktgen: Use "grep -E" instead of "egrep" The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this up by moving the related file to use "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl samples/pktgen` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang Link: https://lore.kernel.org/r/1668826504-32162-1-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Paolo Abeni --- samples/pktgen/functions.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/samples/pktgen/functions.sh b/samples/pktgen/functions.sh index 933194257a24..dd4e53ae9b73 100644 --- a/samples/pktgen/functions.sh +++ b/samples/pktgen/functions.sh @@ -191,7 +191,7 @@ function extend_addr6() fi # if shrink '::' occurs multiple, it's malformed. - shrink=( $(egrep -o "$sep{2,}" <<< $addr) ) + shrink=( $(grep -E -o "$sep{2,}" <<< $addr) ) if [[ ${#shrink[@]} -ne 0 ]]; then if [[ ${#shrink[@]} -gt 1 || ( ${shrink[0]} != $sep2 ) ]]; then err 5 "Invalid IP6 address: $1" -- cgit v1.2.3
