Subject: tools/vm/slabinfo-gnuplot: use "grep -E" instead of "egrep"
From: Tiezhu Yang <yangtiezhu@xxxxxxxxxxx>
commit a435874bf626f55d7147026b059008c8de89fbb8 upstream.
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 tools/vm`
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
