Ubuntu find files

本文介绍了在Linux系统中使用find命令及locate等工具快速定位特定文件的方法。通过find命令结合通配符可以精确查找目标文件,此外,利用locate及其变种如slocate、mlocate能够更高效地搜索文件,但需注意这些工具依赖于预先建立的索引。

For example, we need to find a file called *.pem

We could use this method though a little bit slow:

find / -name "*.pem"


locate and variants need index files, but they work -really- faster. 'locate' is from GNU findutils. 'slocate' was recommended up to etch; it was a more 'secure' version of locate, 

users will not see files that they do not have acess to. 'mlocate' is recommended in lenny and newer, mlocate has a more efficient indexing mechanism.

sudo updatedb     #to update the index

mlocate *.pem
