[root@yanghsia root]#whereis ls (# 定位ls命令的位置) ls:/bin/ls (# ls位于/usr/bln目录下) whereis命令不是通过查找磁盘上的所有文件来实现定位的,你可以随便指定一个可执行文件,估计whereis会找不到,这是因为whereis是根据环境变量PATH来查找文件的,而PATH通常设置成存放命令的那些路径,如 /bin、/usr...
帮助中心 >产品文档 >数据库 >相关技术支持 >Linux whereis命令 whereis 命令可以帮助用户寻找某一命令的二进制文件,源码以及帮助页面。下面是它的格式: whereis [options] [-BMS directory... -f] name... 这是这一命令的 man 页面给出的解释:
--skip-tilde Skip directories in PATH that start with a tilde. --show-dot Don't expand a dot to current directory in output. --show-tilde Output a tilde for HOME directory for non-root. --tty-only Stop processing options on the right if not on tty. --all, -a Print all matches ...

which 查看可执行文件的位置,从全局环境变量PATH里面查找对应的路径,默认是找 bash内所规范的目录 whereis 查看文件的位置,配合参数-b,用于程序名的搜索,从linux数据库查找。 locate 配合数据库查看文件位置。 find 实际搜寻硬盘查询文件名称,效率低。 which常用
Without users, Linux isn’t very useful. Further, the $HOME directory is a key part of the user information. As such, knowing when and how it’s set can be important for the correct function of many scripts and commands. In this tutorial, we explore the $HOME environment variable, how...
Hey, I am somewhat new to Ubuntu/linux and installed and activated Matlab for the first time. The installation process using the GUI installer for whatever reason wouldn't allow me to do it as root, so I created a MATLAB folder in my Documents directory to ins...
The home interface is auto-connected on classic systems. It is not auto-connected on Ubuntu Core. Snaps without the home interface declared and/or connected cannot access the disk. The SNAP_USER_DATA directory will still be created and exist in the user’s home directory. However, it will ...
Where is my block 现在已知测试数据在272号ASM file的135号块。数据块为8K的情况下,每个AU可以包含128个块。这就意味着135号块位于第二个virtual extent的第7个块。第二个virtual extent包含3号磁盘的1175号au和2号磁盘的1179号au. 查询磁盘2和3的名字: ...
