P<strong>OS</strong>IX.2, X/Open Portability Guide, <strong>UNIX</strong> <strong>System</strong> V.<br />

<strong>UNIX</strong> <strong>System</strong> V has a compatible mailx utility, whereas Berkeley Software<br />

Distribution (BSD) has a similar utility, known as Mail.<br />

The –F, –r, and –U options; the Copy, echo, followup, Followup, Save, Unread,<br />

and version subcommands; and the allnet, conv, mailserv, onehop, replyall,<br />

sendmail, and sendwait variables are extensions of the P<strong>OS</strong>IX standard.<br />

make — Maintain program-generated and interdependent files<br />

Format<br />

Description<br />

make [–EeinpqrstuVvx] [–k|–S] [–c dir] [–f file] ...<br />

[macro definition ...] [–D macro definition ...] [target ...]<br />

make helps you manage projects containing a set of interdependent files, such as a<br />

program with many source and object files, or a document built from source files,<br />

macro files, and so on. make keeps all such files up to date with one another. If<br />

one file changes, make updates all the other files that depend on the changed file.<br />

Note: This implementation of make features the .P<strong>OS</strong>IX special target to provide<br />

maximum portability. When you specify this target, make processes the<br />

makefile as specified in the P<strong>OS</strong>IX standard. For details, see the description<br />

of .P<strong>OS</strong>IX in “Special Target Directives” on page 404.<br />

In a doublebyte locale, environment variable values, here documents, and the<br />

command line may all contain environment values.<br />
