man ag
速度对比ag>ack>grep
在android全部源码中查找(测试环境20线程32GB内存):
time ag -i activity
real 2m42.568s
user 0m16.049s
sys 1m29.358s
time ack -i activity
real 5m17.780s
user 1m35.830s
sys 0m17.521s
time grep -Hrni activity .
real 49m27.518s
user 43m13.918s
sys 0m38.178s
It searches code about 3–5× faster than ack.
It ignores file patterns from your .gitignore and .hgignore.
If there are files in your source repo you don't want to search, just add their patterns to a .agignore file. *cough* extern *cough*
The command name is 33% shorter than ack!
