This is a quick method to check with using cURL that Nginx/Apache (or any other web server) compression with Nginx ngx_http_gzip_module (gzip), Nginx google/ngx_brotli (br), Apache mod_brotli (br), Apache mod_gzip (gzip) and Apache mod_deflate (deflate) is working. Only the remote server headers are needed. Check that the Nginx/Apache Compression is Working Get headers curl -s -I -H 'Accept-Encoding: br,gzip,deflate' https://www.if-not-true-then-false.com -s option silent, disable progress bar. -I option which will make just HEAD request to server and get headers. -H option add header for accept content-encoding br, gzip and deflate.

This is quick tip, howto list contents of tar, tar.gz and tar.bz2 files without unpacking file. This is very useful on server environment where any graphical tool is not available. This method is also very useful when tar, tar.gz or tar.bz2 packages are really big, something like hundreds of megabytes or gigabytes (for example backups). Overall, the key is the tar command with -t option. List the Contents of tar File List tar contents short command tar -tvf archive.tar List tar contents long command tar --list --verbose --file=archive.tar Parameters: -t, –list – list the contents of an archive -v, –verbose – verbosely list files processed -f, –file=ARCHIVE – use archive file or device ARCHIVE Example output: -rw-r--r-- foo/bar 7011 2010-10-01 01:19 pax/regtype1 -rw-r--r-- 1000/tarfile 7011 2010-10-01 01:19 pax/regtype2 -rw-r--r-- tarfile/tarfile 7011 2010-10-01 01:19 pax/regtype3 -rw-r--r-- tarfile/tarfile 7011 2010-10-01 01:19 pax/regtype4 -rw-r--r-- tarfile/tarfile 0 2010-10-01 01:19 misc/eof List the Contents of tar.gz File List tar.gz contents short command tar -ztvf archive.tar.gz List tar.gz contents long command tar --gzip --list --verbose --file=archive.tar Parameters: -z, –gzip – filter the archive through gzip -t, –list – list the contents of an archive -v, –verbose – verbosely list files processed -f, –file=ARCHIVE – use archive file or device ARCHIVE Example output: drwxr-xr-x tarfile/tarfile 0 2003-01-06 01:19 ustar/dirtype/ drwxr-xr-x tarfile/tarfile 255 2003-01-06 01:19 ustar/dirtype-with-size/ hrw-r--r-- tarfile/tarfile 0 2003-01-06 01:19 ustar/lnktype link to ustar/regtype lrwxrwxrwx tarfile/tarfile 0 2003-01-06 01:19 ustar/symtype -> regtype brw-rw---- tarfile/tarfile 3,0 2003-01-06 01:19 ustar/blktype List the Contents of tar.bz2 File List tar.bz2 contents short command tar -jtvf archive.tar.bz2 List tar.bz2 contents long command tar --bzip2 --list --verbose --file=archive.tar Parameters: -j, –bzip2 – filter the archive through bzip2 -t, –list – list the contents of an archive -v, –verbose – verbosely list files processed -f, –file=ARCHIVE – use archive file or device ARCHIVE Example output: -rw-r--r-- tarfile/tarfile 86016 2003-01-06 01:19 gnu/sparse -rw-r--r-- 1000/100 7011 2003-01-06 01:19 misc/regtype-old-v7 -rw-r--r-- tarfile/tarfile 7011 2003-01-06 01:19 misc/regtype-hpux-signed-chksum -rw-r--r-- 1000/100 7011 2003-01-06 01:19 misc/regtype-old-v7-signed-chksum drwxr-xr-x 1000/100 0 2003-01-06 01:19 misc/dirtype-old-v7/ -rw-r--r-- tarfile/tarfile 7011 2003-01-06 01:19 misc/regtype-suntar -rw-r--r-- lars/users 7011 2003-01-06 01:19 misc/regtype-xstar
