執行下面指令，觀看「pcmanfm-qt」的使用說明。
$ man pcmanfm-qt
可以執行的有三種
$ pcmanfm-qt --desktop-pref=general
$ pcmanfm-qt --desktop-pref=bg
$ pcmanfm-qt --desktop-pref=advanced
下載 「Source Package: pcmanfm-qt」
執行下面指令，下載「Source Package: pcmanfm-qt」。
$ apt-get source pcmanfm-qt
會下載下面三個檔案
- pcmanfm-qt_0.12.0-5.debian.tar.xz
- pcmanfm-qt_0.12.0-5.dsc
- pcmanfm-qt_0.12.0.orig.tar.xz
並且解開到「pcmanfm-qt-0.12.0」這個資料夾。
–desktop-pref
執行下面指令，找尋跟「general」相關的檔案。
$ grep 'general' pcmanfm-qt-0.12.0/* -R -n
