ddrescue:tldr:d9ddf

This command uses the ddrescue utility with certain options to perform data recovery from one storage device to another. Here's what each part of the command means:

• sudo: This command runs the subsequent command with administrative privileges. It may prompt for the user's password.

• ddrescue: It is the name of the utility used for data recovery.

• --force: This option tells ddrescue to overwrite the output device (/dev/sdY) even if it contains data. Use with caution as existing data will be lost.

• --no-scrape: This option makes ddrescue skip reading data from the source device (/dev/sdX) when errors occur. It helps to speed up the recovery process.

• ${-dev-sdX}: It represents the path to the source device from which data will be recovered. Replace ${-dev-sdX} with the appropriate source device path such as /dev/sda or /dev/sdb.

• ${-dev-sdY}: It represents the path to the destination device where recovered data will be written. Replace ${-dev-sdY} with the appropriate destination device path.

• ${path-to-log-txt}: It represents the path where the log file containing recovery status will be stored. Replace ${path-to-log-txt} with the desired location and filename of the log file. For example, /path/to/log.txt.

By executing this command, ddrescue will start recovering data from the source device to the destination device, and it will create a log file to keep track of the recovery progress.
