Use gzip to uncompress svgz file: unknown suffix I tried to uncompress a .svgz file using gzip, but encountered gzip: p1.svgz: unknown suffix -- ignored.

$ gzip -d p1.svgz
gzip: p1.svgz: unknown suffix -- ignored


I added the suffix .gz to the .svgz file, and still didn't work.

$ gzip -d p1.svgz.gz 
gzip: p1.svgz.gz: not in gzip format


Here is the header of my .svgz file.

&lt;svg viewBox="0 0 1172 1600" version="1.1" preserveAspectRatio="xMinYMin meet" text-rendering="geometricPrecision" class="p1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"&gt;&lt;defs&gt;&lt;style type="text/css"&gt;text{white-space:pre;font-size:16px;font-weight:normal;font-style:normal;fill:none;unicode-bidi:bidi-override}@font-face{font-family:"p1_g_d0_f1";src:url("data:application/font-woff;charset=utf-8;


file p1.svgz returns p1.svgz: SVG Scalable Vector Graphics image.
If you already can read the header of the file with head or cat, the file is not compressed at all.
