On Linux I'm extracting files from a tar archive using

tar -xC / -f /tarFile.tar someFolder/[HD] video1.mp4

This works always fine but not in this case where file name contains square brackets. Tar response is

someFolder/[HD] video1.mp4: not found in archive

The file is extracted fine if I remove the square brackets.

I already tried both escaping all characters with \ and surrounding file name with '. No luck.

Any hint? Thanks

    Can you share which tar --version and shell you use (echo $SHELL)? Can you include the version of commands which you tried with quoting and escaping?

    Is that really the command you typed? It seems like you must have quoted or escaped the space in the filename, otherwise it would see someFolder/[HD] and video1.mp4 as separate arguments.

The first command you have provided will attempt to extract two or three files:

someFolder/H
someFolder/D
video1.mp4

If you enclose filename in single quotes (') the tar program will see the [HD] and process it as a glob wildcard meaning "Either H or D". It will therefore attempt to extract two files:

someFolder/H video1.mp4
someFolder/D video1.mp4

Quoting the filename and using the --no-wildcards flag will suppress these attempted expansions:

tar -xC / -f /tarFile.tar 'someFolder/[HD] video1.mp4' --no-wildcards

Replace square brackets with the wildcard characters (such as ? or *), e.g.

tar -x -C/ -v -f tarFile.tar 'someFolder/?HD? video1.mp4'

or:

tar -x -C. -v -f tarFile.tar 'someFolder/*video1.mp4'

To confirm the filename, you can list the archive file by:

tar -t -f tarFile.tar | grep mp4$

  • A tar implementation that implements pattern matching in extract mode is broken.
