2637 fg
2638 fg
2639 sed -i "s/(.*.cpp)(:)([0-9]*)(:)(.*)/sed -i "3s/new/HPR_NEW_NOTHROW/g"           1/g" new-1.sh
2640 fg
2641 sed -i "s/(.*.h)(:)([0-9]*)(:)(.*)/sed -i "3s/new/HPR_NEW_NOTHROW/g"           1/g" new-1.sh
2642 fg
2643 sed -i "s/(.*.cxx)(:)([0-9]*)(:)(.*)/sed -i "3s/new/HPR_NEW_NOTHROW/g"           1/g" new-1.sh

sed -i "s/(.*.cpp)(:.*:)(.*)/13/g" delete1.sh

sed -i "s/(.*.cpp)(.*delete)(.*)/delete3 1/g" delete1.sh

5186 sed -i "s/(.*delete )(p.*)(;)(.*)/12;/HPR_DELETE(2);/g"4/g" delete1.sh
5187 fg

sed全匹配单词替换：

sed -i 's/<memalign>/HPR_Memalign/g' b.txt

grep -w abc file

del_maohao()
{
    sed -i "s/(.*.cpp):.*/1/g" free.sh.bak
    sed -i "s/(.*.c):.*/1/g" free.sh.bak
    sed -i "s/(.*.h):.*/1/g" free.sh.bak
}

批量重命名

批量修改

sed -i "s/xml/gx_xml/g" `grep xml -rl .`  
sed -i "s/libgx_xml.spec.in/libxml.spec.in/g" `grep libgx_xml.spec.in -rl .`

rename "s/xml/gx_xml/" * 
rename "s/xml/gx_xml/" `find . -name "*xml*"`
