echo off rem rem ALIASES.BAT -- 4DOS Sample Alias File rem rem rem The aliases in this file are designed to give you some examples of rem how 4DOS aliases can be used and the power they have. It is not rem intended to be an exhaustive list, and many of these may not be rem appropriate for your needs. But they should give you a feel for how rem to use aliases to help get your work done. rem rem CAUTION: These aliases are EXAMPLES. We do NOT promise that they rem will work properly when run on your system. They are simply intended rem to show what's possible and give you a feel for how to write your rem own set of aliases. You may find some of them useful, but others rem may fail or have unintended effects when they are run on a system rem other than the one they were designed for. rem rem We suggest you put your standard aliases are in a self-contained rem batch file like this one which can be invoked from AUTOEXEC. That rem way the file can also be re-invoked after it is edited, to re- rem install the aliases. rem rem rem First, delete all previous aliases. rem unalias * rem rem The next few aliases set up some directory commands that provide rem shorthand ways to view the directory in several different formats rem (see the DIR command in the manual for more details). rem rem Note that none of these aliases has any arguments specified (%1, rem %2, etc.). This means that all arguments on the actual command line rem will be appended to the alias text. For example: rem rem d2 x* rem rem is equivalent to: rem rem dir /2 x* rem rem and: rem rem d2 x* y* z* rem rem is equivalent to: rem rem dir /2 x* y* z* rem alias d dir /p alias d2 dir /2 alias de dir /oe alias whereis dir /dp rem rem The following aliases are more shorthand: dd and du (directory rem down and directory up) for pushd and popd, l for list, etc. rem alias dd pushd alias du popd alias l list alias clr mode mono rem rem Most of the next few aliases use arguments. Note that the ones rem which do use arguments have the alias text in back-quotes. These rem are back-quotes, like this `` not single quotes like this ''; they rem are the character above the tilde ~~ on most PC keyboards. rem rem Without the back-quotes the argument names (%1, %2, etc.) will be rem filled in when the alias is created instead of when it is run. rem You can accomplish the same effect as the back-quotes by using rem two % signs in a row. For example the "ov" alias below is written rem as: rem `cd ..\%1` rem rem but could also be written as: rem rem cd ..\%%1 rem rem Here's what these aliases do: rem rem sdel: Allows you to select files for deletion from a subset rem of files as specified in the command argument. For rem example: rem rem sdel *.obj rem rem will allow you to select files to delete from a list rem of all .obj files. (See the SELECT command in the rem manual for more details). rem rem up: Moves "up" in the directory tree, i.e. to the parent rem directory. rem rem ov: Moves "over" in the directory tree, to another subdi- rem rectory which has the same parent as the current rem directory. rem alias sdel `select del (%1)` alias up cd .. alias ov `cd ..\%1` rem rem The next two aliases show how arguments can be passed to commands. rem In both cases the argument given when the alias is invoked is passed rem to the program at the appropriate place in its command string. rem rem Note another effect of the back-quotes in the lp alias: they cause rem the redirection symbol > to be executed when the alias is invoked. rem Without the back-quotes this symbol would redirect the output from rem the alias command itself, which would be meaningless. rem alias lp `lpr -u %1 >lpt1` alias ps `d:\peri\ps /t:%1 /e:4` rem rem The next few aliases demonstrate several things. Some use the rem command separator character ^ to include multiple commands in rem the alias. The last two (pc and back) use the alias called px rem to do their job. In fact px was designed for "internal" use by rem other aliases in this file, though it could be used elsewhere as rem well. Note that, while px is set up before it is referenced in rem other aliases, this is not really necessary, because any command rem in one alias which refers to another is handled when the alias is rem invoked, not when it is set up with the alias command. rem rem Here's what each alias does: rem rem nd: Creates a new directory below the current directory, rem then changes to it. rem rem w: Saves the current directory, changes to the wp rem directory on drive c:, runs the wp program using rem the first argument on the command line, and rem restores the original directory when done. rem rem zap: Deletes all the .bak files in the current directory, rem then does a wide directory listing. rem rem px: "Pushes" a different directory, executes a command, rem and then goes back to the original directory. See rem PUSHD and POPD in the manual for more details. rem rem pc: Changes to the \comm directory on drive c:, runs rem the program called pcomm, then returns to the rem drive and directory in use when the command was rem executed. rem rem back: Changes to the \backup directory on drive d:, runs rem the program called tape, then returns to the previous rem drive and directory. rem alias nd `md %1^cd %1` alias w `pushd c:\wp^wp %1^popd` alias zap `del *.bak^dir /w` alias px `pushd %1^%2^popd` alias pc px c:\comm pcomm alias back px d:\backup tape rem rem The following aliases make use of the %& argument. This argument rem means "all of the arguments on the command line". For example: rem rem zap2 *.bak *.lst *.bk! rem rem expands to: rem rem erase *.bak *.lst *.bk!^chkdsk^dir /w rem alias zap2 `erase %&^chkdsk^dir /w` alias ed `edit %&^del *.bak` rem rem The following two aliases, taken from page 22 of the manual, show rem how to combine alias with keystack to invoke a program and pass rem parameters to it. See the manual for details on what they do. rem Note that the 0s in the keystack strings simulate an empty keyboard rem buffer; the 13s are carriage returns. rem alias 321 `keystack 0 13 0 13 0 13 0 13 0 13 "/fr" 0 "%1" 13^123` alias drpt `pushd c:\data^keystack "use times index times" 13 "report form timerep to print" 13 "quit" 13^dbase^popd`
