案例
非递归搜刮包含指定字符串的文件
膳绫擎案例中忽视了所有的子目次。所谓递归搜刮就是指同时搜刮所有的子目次。
第一个例子让我们来搜刮 /etc/ 目次下所有包含 stretch 字符串的文件,但不去搜刮个中的子目次:
# grep -s stretch /etc/*/etc/os-release:PRETTY_NAME="Debian GNU/Linux 9 (stretch)"/etc/os-release:VERSION="9 (stretch)"
grep 的 -s 选项会在发明不存在或者不克不及攫取的文件时隐蔽报错信息。结不雅显示除了文件名之外,还有包含请求字符串的行也被一发誓出了。
递归地搜刮包含指定字符串的文件
下面的敕令会在 /etc/ 及其子目次中搜刮包含 stretch 字符串的文件:
# grep -R stretch /etc/*/etc/apt/sources.list:# deb cdrom:[Debian GNU/Linux testing _Stretch_ - Official Snapshot amd64 NETINST Binary-1 20170109-05:56]/ stretch main/etc/apt/sources.list:#deb cdrom:[Debian GNU/Linux testing _Stretch_ - Official Snapshot amd64 NETINST Binary-1 20170109-05:56]/ stretch main/etc/apt/sources.list:deb http://ftp.au.debian.org/debian/ stretch main/etc/apt/sources.list:deb-src http://ftp.au.debian.org/debian/ stretch main/etc/apt/sources.list:deb http://security.debian.org/debian-security stretch/updates main/etc/apt/sources.list:deb-src http://security.debian.org/debian-security stretch/updates main/etc/dictionaries-common/words:backstretch/etc/dictionaries-common/words:backstretch's/etc/dictionaries-common/words:backstretches/etc/dictionaries-common/words:homestretch/etc/dictionaries-common/words:homestretch's/etc/dictionaries-common/words:homestretches/etc/dictionaries-common/words:outstretch/etc/dictionaries-common/words:outstretched/etc/dictionaries-common/words:outstretches/etc/dictionaries-common/words:outstretching/etc/dictionaries-common/words:stretch/etc/dictionaries-common/words:stretch's/etc/dictionaries-common/words:stretched/etc/dictionaries-common/words:stretcher/etc/dictionaries-common/words:stretcher's/etc/dictionaries-common/words:stretchers/etc/dictionaries-common/words:stretches/etc/dictionaries-common/words:stretchier/etc/dictionaries-common/words:stretchiest/etc/dictionaries-common/words:stretching
