You may want to **use **these commands even if they exist in the environment for the following reasons
You may want to **avoid **these commands for the following reasons
- There are some things these commands cannot do which the native OS commands can, due to being based (limited by) java API's. For example the [[CommandChmod chmod]] command cannot set group permissions or setuid modes.
- [[CommandChmod chmod]] - Change file permissions

No Differences

Revision [597]

Edited on 2009-05-30 08:49:42 by DavidLee
Additions:
- Consistant with xmlsh internal environment model
- Since these commands are implemented using the internal API they will produce results more consistant with the internal model. For example the cygwin "pwd" command can give different results then the xmlsh posix "pwd" command due to cygwin's differing model of the filesystem.

Additions:
====Importing====
To use the Posix commands you need to [[CommandImport import]] them into either the global namespace or a local namespace.
Its recommended that you use a local namespace so that you still have access to the system commands of the same name.
To import into the posix namespace
%%
import commands posix=posix
%%
To import into the global namespace
%%
import commands posix
%%
====Advantages / Disadvantages ====
You may want to use these commands even if they exist in the environment for the following reasons
- They are very fast.
- These commands are run in the shell's JVM and do not require starting a subprocess.
- No dependancy on environment
- You can use these commands to write scripts that do not depend on them existing in the environment. The test cases use these commands so they can run on Windows without presuming you have cygwin installed.

You may want to avoid these commands for the following reasons
- They are less feature-full then the coresponsing OS commands.
- They are not as mature, these commands are a simple implementation using core java methods and may not be as roboust as the OS commands.
====Commands====
- [[CommandCp cp]] - copy one or more files
- [[CommandCat cat]] - copy or concatenate files
- [[CommandCp mv]] - Move/Rename files
- [[CommandRm rm]] - Remove/Delete files
- [[CommandMkdir mkdir]] - Create directories
- [[CommandTouch touch]] - create and update timestamp of a file
Deletions:
- [[CommandCsv2xml csv2xml]] - convert csv file to xml
