git reset makes the current branch point to some specific revision or branch. git reset --hard makes the current branch point to some specific revision or branch, and replaces the current working files with the files from that branch. git merge merges files from a given branch into the current branch. git push
update: Update the files in a working copy with the latest version from a repository; lock: Lock files in a repository from being changed by other users; add: Mark specified files to be added to repository at next commit; remove: Mark specified files to be removed at next commit (note: keeps cohesive revision history of before and at the remove.)
Allows a user to specify customized default parameters for the DIR command, including file specifications. Preset default switches can be overridden by providing the negative switch on the command line. For example, if %DIRCMD% contains the /W switch, then it can be overridden by using DIR /-W at the command line.
If a 0410 a.out executable file has the sticky bit (mode bit 01000) set, the operating system will not delete the program text from the swap area when the last user process terminates. If a 0413 a.out or ELF executable file has the sticky bit set, the operating system will not delete the program text from memory when the last user process ...
The file owner is 'root' and the SUID permission is set (the '4') - so the file is executed as 'root'. The reason an executable would be run as 'root' is so that it can modify specific files that the user would not normally be allowed to, without giving the user full root access. A default use of this can be seen with the /usr/bin/passwd binary ...
It is important to note here that, if invalid credentials are supplied then a javax.security.auth.login.FailedLoginException should be thrown (rather than returning false, which indicates that this login module should be ignored, which potentially allows authentication to succeed).
It uses the MultiVersion File System (MVFS), which is a virtual file system that transparently determines which versions of files and directories should be in the workspace and orchestrates file access and lifecycle. The MVFS is used in LAN deployments for dynamic views and in LAN or WAN deployments for automatic views.
Change its acoustic management, at the cost of read/write performance (some hard drives and SSDs might ignore this setting though.): sudo hdparm -M 128 /dev/sda If the disk synchronisation intervals are too short, then even small amounts of data will be written to disk which can have severe consequences for its lifespan.
