X/Open does not specify the format of the compiled terminal description. In fact, it does not even mention the common tic or infocmp utilities. [ 6 ] [ 7 ] Because the compiled terminfo entries do not contain metadata identifying the indices within the tables to which each capability is assigned, they are not necessarily compatible between ...
The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user. If pushd is not provided with a path argument , in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories.

[8] /tmp: Directory for temporary files (see also /var/tmp). Often not preserved ...
Standard input is a stream from which a program reads its input data. The program requests data transfers by use of the read operation. Not all programs require stream input. For example, the dir and ls programs (which display file names contained in a directory) may take command-line arguments, but perform their operations without any stream ...
An fwrite of data obtained from the buffer by fread will not be obtaining the data from the file itself, and some other user could have changed it. Both could use flock to ensure exclusive access, which prevents simultaneous writes, but since the reads are reading from the buffer and not the file itself, any data changed by user #1 can be lost ...
COMMAND.COM, the original Microsoft command line processor introduced on MS-DOS as well as Windows 9x, in 32-bit versions of NT-based Windows via NTVDM; cmd.exe, successor of COMMAND.COM introduced on OS/2 and Windows NT systems, although COMMAND.COM is still available in virtual DOS machines on IA-32 versions of those operating systems also.
