csidem: How to Delete Certain Files and Not All
Hey there, readers!
Welcome to our in-depth guide on how to selectively delete files using csidem. Whether you’re a seasoned pro or just starting out, we’ve got you covered. Let’s dive right in!
Section 1: Understanding csidem’s Deletion Capabilities
csidem Basics: File Deletion Syntax
csidem offers a powerful command-line interface for managing files and directories. To selectively delete files, we use the -delete flag followed by the appropriate criteria. The general syntax looks like this:
csidem -delete [criteria] [path]
Selective File Deletion Criteria
The [criteria] parameter allows us to specify which files to delete. Here are some common criteria options:
- glob pattern: Matches files based on a specified pattern (e.g.,
*.txt) - regular expression: Matches files based on a regular expression (e.g.,
.*\.jpg$) - property: Matches files based on a specific property (e.g.,
size < 1MB)
Section 2: Deleting Files Based on Specific Criteria
Deleting by File Type
Let’s say you want to delete all PNG files within a directory. You can use the following command:
csidem -delete "*.png" /path/to/directory
Deleting by Size
To remove all files smaller than 2MB, use this command:
csidem -delete "size < 2MB" /path/to/directory
Deleting by Last Modification Date
Or, you can delete files that haven’t been modified in over a week:
csidem -delete "mtime < -7d" /path/to/directory
Section 3: Advanced csidem Deletion Techniques
Excluding Certain Files or Directories
Sometimes, you may want to exclude specific files or directories from deletion. Use the -exclude flag for this:
csidem -delete "*.txt" /path/to/directory -exclude /path/to/excluded_directory
Deleting Recursively
To delete files recursively within subdirectories, add the -r flag:
csidem -delete "*.log" /path/to/directory -r
Using the -force Option
If you’re sure about deleting the files without prompting, use the -force option:
csidem -delete "*.tmp" /path/to/directory -force
Section 4: Detailed Breakdown of Deletion Criteria
| Criteria | Description | Example |
|---|---|---|
| glob pattern | Matches files based on a specified pattern | *.png |
| regular expression | Matches files based on a regular expression | .*\.jpg$ |
| size | Matches files based on size | size < 1MB |
| mtime | Matches files based on last modification date | mtime < -7d |
| metadata | Matches files based on metadata properties | metadata=owner:user |
| content | Matches files based on content | content=pattern |
| exists | Matches files that exist | exists=true |
| path | Matches files based on path | path=/path/to/file |
