It looks like one possible answer is, unsurprisingly, curl: $ curl http://example.com/ –silent –write-out “%{size_download}\n” –output /dev/null 31032 $ curl http://example.com/ –silent -H “Accept-Encoding: gzip,deflate” –write-out “%{size_download}\n” –output /dev/null 2553 In the second case the client tells the server that it supports content encoding and you can see that the response was indeed shorter, compressed.
Edit There appears to be a better LZW solution that handles Unicode strings correctly at http://pieroxy.net/blog/pages/lz-string/index.html (Thanks to pieroxy in the comments). I don’t know of any gzip implementations, but the jsolait library (the site seems to have gone away) has functions for LZW compression/decompression. The code is covered under the LGPL. // LZW-compress a … Read more
Why use deflate instead of gzip for text files served by Apache? The simple answer is don’t. RFC 2616 defines deflate as: deflate The “zlib” format defined in RFC 1950 in combination with the “deflate” compression mechanism described in RFC 1951 The zlib format is defined in RFC 1950 as : 0 1 +—+—+ |CMF|FLG| … Read more
tar -zcvf compressFileName.tar.gz folderToCompress everything in folderToCompress will go to compressFileName Edit: After review and comments I realized that people may get confused with compressFileName without an extension. If you want you can use .tar.gz extension(as suggested) with the compressFileName
Configuration You can enable GZIP compression entirely in your Web.config file. This is particularly useful if you’re on shared hosting and can’t configure IIS directly, or you want your config to carry between all environments you target. <system.webServer> <httpCompression directory=”%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files”> <scheme name=”gzip” dll=”%Windir%\system32\inetsrv\gzip.dll”/> <dynamicTypes> <add mimeType=”text/*” enabled=”true”/> <add mimeType=”message/*” enabled=”true”/> <add mimeType=”application/javascript” … Read more
If you use Python3x then string is not the same type as for Python 2.x, you must cast it to bytes (encode it). plaintext = input(“Please enter the text you want to compress”) filename = input(“Please enter the desired filename”) with gzip.open(filename + “.gz”, “wb”) as outfile: outfile.write(bytes(plaintext, ‘UTF-8’)) Also do not use variable names … Read more
I solved that problem by setting the Command Line Tools in Xcode. Go to: Xcode > Preferences > Locations And select the command line tool from the dropdown. If you have only one version of Xcode installed, there should be only one option. If you have several versions of Xcode, then you must choose the … Read more
You can also use the tar flag “–use-compress-program=” to tell tar what compression program to use. For example use: tar -c –use-compress-program=pigz -f tar.file dir_to_zip
You can use the option -C (or –directory if you prefer long options) to give the target directory of your choice in case you are using the Gnu version of tar. The directory should exist: mkdir foo tar -xzf bar.tar.gz -C foo If you are not using a tar capable of extracting to a specific … Read more
Use the -C switch of tar: tar -czvf my_directory.tar.gz -C my_directory . The -C my_directory tells tar to change the current directory to my_directory, and then . means “add the entire current directory” (including hidden files and sub-directories). Make sure you do -C my_directory before you do . or else you’ll get the files in … Read more
