How to unzip a file (ex: foo.zip) to a folder with the same name (foo/)?
Basically, I want to create an alias of unzip that unzips files into a folder with the same name (instead of the current folder). That's how Mac's unzip utility works and I want to do the same in CLI.
I use unar for this; by default, if an archive contains more than one top-level file or directory, it creates a directory to store the extracted contents, named after the archive in the way you describe:
unar foo.zip You can force the creation of a directory in all cases with the -d option:
unar -d foo.zip Alternatively, a function can do this with unzip:
unzd() { if [[ $# != 1 ]]; then echo I need a single argument, the name of the archive to extract; return 1; fi target="${1%.zip}" unzip "$1" -d "${target##*/}" } The
target=${1%.zip} line removes the .zip extension, with no regard for anything else (so foo.zip becomes foo, and ~/foo.zip becomes ~/foo). The
${target##*/} parameter expansion removes anything up to the last /, so ~/foo becomes foo. This means that the function extracts any .zip file to a directory named after it, in the current directory. Use unzip $1 -d "${target}" if you want to extract the archive to a directory alongside it instead.
unar is available for macOS (along with its GUI application, The Unarchiver), Windows, and Linux; it is packaged in many distributions, e.g. unar in Debian and derivatives, Fedora and derivatives, community/unarchiver in Arch Linux.
parallel unar {} ::: *.zip *.rar *.7z) Just one another variant to do that with a 1-liner for multiple zip files in current dir:
for f in *.zip; do unzip "$f" -d "${f%.zip}"; done For just one file (i.e. to use in a function) it would be:
unzip "$1" -d "${1%.zip}" Use unzip -d exdir zipfile.zip to extract a zipfile into a particular directory. In principle from reading your post literally you could write a function like this:
unzip_d () { unzip -d "$1" "$1" } Since you want the .zip extension removed though, you can use special variable syntax to do that:
unzip_d () { zipfile="$1" zipdir=${1%.zip} unzip -d "$zipdir" "$zipfile" } 
unzip -d foo foo.zip.
