我想rm
可能是个别名rm -i
。“常规”部分没有特别的含义,仅表示它不是管道,设备,插座或任何其他“特殊”部分。
file /etc/passwd
或中所示file /dev/null
。
任何通过测试(-f
)的文件都是常规文件:
$ test -f afile.zip && echo regular
regular
如果浏览手册页,test
将看到所有各种类型的文件。
您还可以使用以下stat
命令检查文件是否正常:
$ stat afile.zip
File: `afile.zip'
Size: 1512 Blocks: 8 IO Block: 4096 regular file
Device: fd02h/64770d Inode: 10370668 Links: 1
Access: (0664/-rw-rw-r--) Uid: ( 500/ saml) Gid: ( 501/ saml)

要了解更多有关常规文件和其他可能类型之间的区别的信息,请查看的手册页stat
。确保查看程序员手册的手册页,而不是实际stat
命令的手册页。
$ man 2 stat
