LHA is a command-line utility that is used to compress or decompress files in the LZH format. It is commonly used in Linux systems to compress files for backup purposes or to reduce the size of large files. The LHA command is similar to the more popular gzip and bzip2 commands, but it is specifically designed for the LZH format.
Overview
The LHA command can be used to compress or decompress files in the LZH format. To compress a file, use the following syntax:
lha -c <filename.lzh> <file1> <file2> <file3> ...
This command will create a compressed LZH archive with the specified filename, containing the files listed after the filename. For example, to compress the files file1.txt
, file2.txt
, and file3.txt
into an archive called archive.lzh
, use the following command:
lha -c archive.lzh file1.txt file2.txt file3.txt
To decompress an LZH archive, use the following syntax:
lha -x <filename.lzh>
This command will extract all the files from the specified LZH archive into the current directory. For example, to extract the files from an archive called archive.lzh
, use the following command:
lha -x archive.lzh
Options
The LHA command has several options that can be used to modify its behavior. The available options are listed in the table below:
Option | Description |
---|---|
-c | Compress files into an LZH archive |
-x | Extract files from an LZH archive |
-v | Verbose mode (print information about the compression/decompression process) |
-t | Test the integrity of an LZH archive |
-d | Delete the original files after compression |
-s | Set the compression level (0-3, with 3 being the highest compression) |
Troubleshooting Tips
If you encounter issues using the LHA command, try the following troubleshooting tips:
- Make sure you have the LHA command installed on your system. If it is not installed, you can install it using your system’s package manager.
- Double-check the syntax of your command to make sure it is correct.
- If you are having trouble extracting files from an LZH archive, make sure the archive is not corrupt. You can test the integrity of the archive using the
-t
option.
Notes
- The LHA command is not as widely used as gzip or bzip2, but it can be useful for compressing or decompressing files in the LZH format.
- The LZH format is not as common as other compression formats, but it is still used in some legacy systems and applications.
