Element | Purpose |
+ | Include. Include the trees, paths, segments, files and exts that follow, until the next -. There is an implied + to start. |
- | Exclude. Exclude the trees, paths, segments, files and exts that follow, until the next +. |
tree | absolute or relative name of a directory tree. Process subdirectories too. Tree names many contain the wildcard characters * and ?. It is followed by one or more path names separated by spaces or commas. Tree names containing spaces or commas must be enclosed in quotes. |
path | absolute or relative name of a directory, or file, Subdirectories are not processed. It is followed by one or more path names separated by spaces or commas. Pathnames containing spaces or commas must be enclosed in quotes. Path names many contain the wildcard characters * and ?. There is an implied path command to start. |
segment | name of one leg of a directory, at any depth. Subdirectories are not processed. Segment names many contain the wildcard characters * and ?. It is followed by one or more segment names separated by spaces or commas. Segment names containing spaces or commas must be enclosed in quotes. You can undo previous segment exclusions with + segment *.*. You can undo previous segment inclusions with - segment *.*. |

You can under previous extension inclusions with - extension *.*. |
startswith | A string of characters that starts the names of set of trees, paths, branches, files, or extensions you wish processed/excluded. It operates on the immediately preceding tree, path, segment, branch, file or ext level. |
endswith | A string of characters that ends the names of a set of trees, paths, branches, files, or extensions you wish processed/excluded. It operates on the immediately preceding tree, path, segment, branch, file or ext level. |
regex | A string of characters that ends the names of a set of trees, paths, branches, files, or extensions you wish processed/excluded. It operates on the immediately preceding tree, path, segment, branch, file or ext level. |
Constellation Examples | ||
---|---|---|
Example | Notes | |
E:\env\ | Because of the implied + path command at the start, this is treated as a request to process all the files in the J:\env\ directory but not any of its subdirectories. | |
-ext bat,btm,txt + E:\env\ | Process all the *.bat *.btm and *.txt files in the env directory. | |
- ext bat,btm,txt + E:\env\ E:\sys\ | Process all the files in the env directory except the *.bat *.btm and *.txt files. The list of extensions applies to everything to the rigth, so that list is also used to exclude files from the E:\sys directory. | |
- dir env\scripts\ + file importantscript.srs + path env\ | Presuming the current directory is E:\, files in E:\env and its subdirectories, except env\scripts, but include the file env\scripts\importantscript.srs Note the order. We must specify the path last since the exclusions apply only to items to the right. | |
tree E:\env\ | Process the entire E:\env\ directory tree, i.e. process oll of it subdirectories recursively. | |
tree E:\env\ E:\sys - path E:\env\income tax | Process the entire E:\env\ and E:\sys directory trees, ( presuming E:\sys
is a directory).
It will also include the "J:\income tax\"
directory since the -path command applies only to items to the right. | |
ext .bat .b?m path E:\env\ | Process just .bat and .b?m extensions of the E:\env\ directory. | |
ext .html - file endswith log.html + tree E:\com\mindprod | Process .html files, but not file names that end in log.html in the E:\com\mindprod directory tree. | |
ext .html - file regex (abc|def)[0-9]\\.html + tree E:\com\mindprod | Process the .html files, but exclude any files of the form abc9.html or def9.html. The regexes are quoted with \ as if they appeared in Java source code. | |
- branch .svn + tree E: | Process the entire E: drive, but ignore any directory trees you find headed with a .svn Subversion directory. |
