Package file implements utility routines for file operations and system interactions.
It provides functions to search for files, list block devices, and search mountpoints on both macOS and Linux systems.

Functions ¶
func FindUserData ¶
FindUserData searches for the config file on the system. On macOS, it searches within the "/Volumes" directory. On Linux, it lists block devices and searches their mountpoints and their children mountpoints. If the file is found, its path is returned. If an error occurs during the search, it is returned.
func GetFilePath ¶
GetFilePath searches for a file with the specified name starting from the rootDir. It traverses the directory tree and returns the path of the first matching file found. Hidden directories and files are skipped during the search. If the file is found, its path is returned. If an error occurs during the search, it is returned.
func SearchMountpoints ¶
SearchMountpoints searches for a file with the specified name in the provided mountpoints iterating over them, ignoring certain paths. For valid mountpoints, it calls GetFilePath to find the "user-data" file. If the file is found, its path is returned. If an error occurs, it is returned.
Types ¶
type BlockDevices ¶
type BlockDevices struct {
Blockdevices []struct {
Name string `json:"name"`
MajMin string `json:"maj:min"`
Rm bool `json:"rm"`
Size string `json:"size"`
Ro bool `json:"ro"`
Type string `json:"type"`
Mountpoints []string `json:"mountpoints"`
Children []struct {
Name string `json:"name"`
MajMin string `json:"maj:min"`
Rm bool `json:"rm"`
Size string `json:"size"`
Ro bool `json:"ro"`
Type string `json:"type"`
Mountpoints []string `json:"mountpoints"`
} `json:"children,omitempty"`
} `json:"blockdevices"`
}
BlockDevices is the representation of the block devices on a Linux system as returned by the `lsblk` command, containing information about each block device. If the block device has children (e.g., partitions), they are also included with similar information.
func ListBlockDevices ¶
func ListBlockDevices() (BlockDevices, error)
ListBlockDevices returns a list of block devices on a Linux system by executing the `lsblk` command with the `--json` flag, parsing it's output into a BlockDevices struct. If the command execution or JSON parsing fails, an error is returned.
