TAR command to extract a single file from a .tar.gz

gziptar

Does anyone have a command syntax for extracting 1 file from a .tar.gz that also allows me to place the extracted file in a certain directory? I have Googled this and get too many variations with a lot of forum threads stating the syntax doesn't work. Before I venture on I prefer to know the command will work because I do not want to risk overwriting files and directories already present on my server.

If you're risking overwriting files in production with uncertain results, you're doing something wrong. Test first.

tar zxvf archive.tar.gz path/to/file/in/archive -C /destination/dir

You could try your extract with the -i option to ignore zeros:

The --ignore-zeros (-i) option causes tar to ignore blocks of zeros in
the archive. Normally a block of zeros indicates the end of the archive,
but when reading a damaged archive, or one which was created by cat-ing
several archives together, this option allows tar to read the entire
archive. This option is not on by default because many versions of tar
write garbage after the zeroed blocks.
