Is it possible to create a target directory, similar to mkdir -p, where I can define a non-existent target directory within my tar command, and tar will create the directory for me?

I know I can redirect the output to a directory using tar -C /target/dir, but this doesn't work if the target directory is non-existent.

    If it isn't possible, you could always create a shell alias. – n0pe Nov 25 '11 at 4:02

mkdir -p /target/dir && tar -C /target/dir

    No spoonfeeding, straight and to the point. – Amado Martinez Oct 31 '16 at 6:56

    Minor suggested change: mkdir -p /target/dir && tar -C $_ – Mark Melville Jan 13 '17 at 22:41

  • @Suhayb $_ is a special parameter in Bash that expands to the last argument to the previous command. – ConceptRat May 28 at 4:09

tar -xvf bash.html_node.tar.gz --one-top-level

From man page of tar command

--one-top-level[=DIR]

    Extract all files into DIR, or, if used without argument, into a subdirectory named by the base name of the archive (minus standard compression suffixes recognizable by --auto-compress).

----- test

test 1

tar zxvf ../aaa.tgz --one-top-level
aaa/
aaa/222
aaa/111

tree aaa
aaa/
├── 111
└── 222

// if tgz name same as root_dir of archive, no other effect

test 2

mv ../aaa.tgz ../bbb.tgz

tar zxvf ../bbb.tgz --one-top-level
aaa/
aaa/222
aaa/111

tree bbb
bbb
└── aaa
    ├── 111
    └── 222

// if tgz name not same as root_dir of archive, create a top-level dir

  • Requires GNU tar? Mac default bsd tar does not have this option. – Curtis Yallop Apr 18 at 18:12

This made more sense to me: mkdir -p /create/folder && tar -zxf haroopad-v0.13.0_x64.tar.gz -C /create/testfolder

mkdir makes the folder although I don't quite understand the -p switch. && lets you execute a second command. I used typical tar switches but at the end -C is used to change directories and extract to that location needed.

    The -p switch will not throw an error if the directory already exists. – David Sep 3 '15 at 21:10
  • @David it will also create any leading non-existing directories, i.e. it'll create /create if it doesn't exist. – Antonio Pérez Oct 21 '15 at 13:40

If you don't know the paths to create...
Get the needed paths from the tar file, then create them...

for P in \`tar tvf tarfile.tar |tr -s [:space:] |cut -d' ' -f6\`; do  
    C=\`echo "${P: -1}"\`  #get the last character  
    if [ $C = '/' ]; then  
        echo "Found directory: $P"  
        mkdir -p $P  
    fi  
done
