Difference in Use between pwd and $PWD - Ask Ubuntu The pwd binary, on the other hand, gets the current directory through the getcwd(3) system call which returns the same value as readlink -f proc self cwd To illustrate, try moving into a directory that is a link to another one:
How can I get the current working directory? [duplicate] In cases where PWD is set to the pathname that would be output by pwd -P, if there is insufficient permission on the current working directory, or on any parent of that directory, to determine what that pathname would be, the value of PWD is unspecified Assignments to this variable may be ignored
What is the difference between cwd and pwd? What is the difference between cwd and pwd? I've tried googling it, and one of the answers mentioned that depending on some factor (which I sadly do not remember), the implementation (the code I'm assuming) is not the same?
PATH=$PATH:`pwd` - What happens when this command is executed? Then that will add the current directory (pwd is a command that prints the path of the current directory, and `pwd` will be replaced with the output of pwd) to the PATH variable for the duration of your current shell session (util you close the terminal)
Make pwd result in terms of - Unix Linux Stack Exchange If you're going to do this, I'd strongly recommend naming the resulting command something other than pwd Otherwise, you'll break scripts that expect to use its output in contexts that don't perform tilde expansion
Resolving symbolic links (pwd) - Unix Linux Stack Exchange Your shell has a builtin pwd, which tries to be "smart" After you did a cd to a symlink the internal pwd fakes the output as if you moved to a real directory Pass the -P option to pwd, i e run pwd -P The -P option (for “physical”) tells pwd not to do any symbolic link tracking and display the “real” path to the directory Alternatively, there should also be a real binary pwd, which
