pwgrep 介绍
为了管理我的密码，我写了一个小的 bash/awk 脚本用来管理一个密码数据库并使用 GnuPG 进行加密。使用 pwgrep 的好处是：
- 密码加密
- 密码版本化，不用担心丢失老密码
- Since a versioning system is used, the password database can be used on several hosts at once (automatic synchronization). Even several user can share the same password database. The versioning system will keep track of who was changing which entries and at which time.
- The versioning system to use can be configured (Subversion by default)
- Besides of passwords, pwgrep can also be used for storing a collection of files like certificates
- The file shredding command for secure deleting of temporary files can be configured (shred on Linux and destroy or rm -P on FreeBSD by default)
- Automatic local backup of all database changes (Still access to old data after editing the password database and the network connection to the versioning system is not accessible)
- No need of a GUI (can be used through a SSH session)
- Using only open source software
- Running on all *NIX and alike systems
- Very easy and straight forward to use
