What is a tar.gz File?īefore we dive into the how-to, let’s clarify what a tar.gz file is.
UNTAR COMMAND IN LINUX FOR TAR GZ HOW TO
This article will guide you on how to extract tar.gz files effectively in Linux. But fear not – once you know the steps, extracting tar.gz files is a breeze. One such task is file compression and extraction, especially when dealing with the common tar.gz format. However, for new users, and even for some experienced ones, certain tasks can seem daunting. It’s used widely in servers, embedded systems, and personal computers alike. To extract the files matching the pattern we can use ugrep with options -z, -l, and -format="%s " to list the matching files in the archive, extracting them to folder/another_folder: tar xzf `ugrep -z -l "pattern" -format="%z " is a powerful and flexible operating system, often lauded for its robustness and versatility. To search for files matching pattern in is simply one command: ugrep -z -l "pattern" Supported compression formats: gzip (.gz), compress (.Z), zip,īzip2 (requires suffix. Whose name matches globs, matches file name extensions, matchesįile signature magic bytes, or matches file types, respectively. g, -O, -M, or -t is specified, searches files within archives Matching pathnames of files in archives are output in braces. Or is there a better way to search for a file inside a tar.gz fileĪ grep-compatible utility that searches tarballs directly is ugrep with option -z: -z, -decompressĭecompress files to search, when compressed. gunzip -c | tar tvf - | grep filename | -exec cp /folder/another_folder \ So far I have this, but the copy part of this line gives me an error. After that, I need to copy the file that was searched (if ever I need to search for a file inside a tar.gz file without extracting Tar xvzf -strip-components "$components" "$file_path" & cp "$file_name" /new/location & echo "No files matching $pattern found." & exit 1 So you can count how many components there are before the basename so that you can do a sort of "extract here" operation followed by a copy: pattern=filenameįile_path="$(tar tzf | grep "$pattern" )" The GNU implementation of tar has a -strip-components option that takes a number and strips that many components from the file name before extraction. You can probably do something like this: pattern=filenameįile_path="$(tar tzf 2>/dev/null| grep "$pattern")"Įcho "No files matching $pattern found in archive"
UNTAR COMMAND IN LINUX FOR TAR GZ ARCHIVE
You can't (easily) extract part of an archive to a different location from the one it's been archived under. You can't do this in one step, I'm afraid. This argument too is now wrapped in double quotes to protect it. We now use the switch -wildcards to the 2nd tar so that we can extract based on a pattern rather than just a single file. Also the argument to grep is also not wrapped in double quotes. Grep now includes the switch -E, because we're searching for a regular expression now and not just a single string within the output of tar. This is to protect the *Makefile from getting accidentally expanded. Notice that we've wrapped it in single quotes vs. We're extracting everything that matches '*Makefile'. The above involves a couple of additional changes. Tar ztvf $arc | grep -E "$file" & tar zxvf $arc -C /tmp -wildcards "$file"Ĭonfirmation $ find /tmp/cp210x -ls | grep MakefileĢ6881948 4 -r-r-r- 1 manny manny 171 /tmp/cp210x/Linux_3.x.x_VCP_Driver_Source/MakefileĢ6881960 4 -rw-rw-r- 1 manny manny 388 May 13 01:37 /tmp/cp210x/usb-serial/Makefile Wildcards could also be used if you want to extract a pattern of files. Tar ztvf $arc | grep $file & tar zxvf $arc -C /tmp $fileĬonfirmation $ ll /tmp/cp210x/usb-serial/Makefile Tar ztvf $arc | grep $file & tar zxvf $arc -C /path/to/dir $fileĮxample #1 $ arc=".gz" \įile="ffmpeg" tar ztvf $arc | grep $file & tar zxvf $arc -C /tmp $file If you want to output the extracted file to some other location you can use tar's -C switch. Tar ztvf $arc | grep $file & tar zxvf $arc $file You could do something like this if you wanted to search for the file first, and only if present then extract it. This would then return the name of the file if it existed at all in the archive.
Does your version of tar not support the switch -z? $ tar ztvf | grep fliename
