Linux 下如何找到 Chromium 的二进制 ELF 文件路径

[Arondight]

目前已知发行版的 Chromium ELF 路径如下。

发行版	包名	软件源	ELF
CentOS	chromium	EPEL	/usr/lib64/chromium-browser/chromium-browser
Debian 、 Raspbian	chromium	main	/usr/lib/chromium/chromium
Fedora	chromium	fedora	/usr/lib64/chromium-browser/chromium-browser
Ubuntu	chromium-browser	universe	/usr/lib/chromium-browser/chromium-browser
Arch Linux	chromium	extra	/bin/chromium

具体方法如下。

有的发行版比较麻烦，例如 CentOS 。

$ type chromium-browser 
chromium-browser is /bin/chromium-browser

$ file /bin/chromium-browser 
/bin/chromium-browser: symbolic link to /usr/lib64/chromium-browser/chromium-browser.sh

$ bash -x /usr/lib64/chromium-browser/chromium-browser.sh

$ file /usr/lib64/chromium-browser/chromium-browser

从而确定路径为 /usr/lib64/chromium-browser/chromium-browser 。

有的发行版比较简单，例如 Arch Linux

$ type chromium 
chromium 是 /bin/chromium

$ file /bin/chromium
/bin/chromium: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=b9b52b7c8daa9537a7c763918d4c82a710569578, for GNU/Linux 4.4.0, stripped

从而确定路径为 /bin/chromium 。
