裝過幾個Linux以後，發現Gentoo的色采設置裝備擺設還真的相當悅目

如許子，每次登入bash就會本身去找bashrc來更新設定檔囉！

這時候候，只需要在本身的家目次再設立建設一個 .bash_profile

若是翻譯公司碰到了跟我一樣的問題

所以參數設定的前後，必然要以 \[ & \] 作為開首與結尾！！

這代表PS1參數設定不准確，讓Bash無法准確判讀哪邊是non-printing characters

還記得本文最上方那張圖嗎？

不外，你會發現，第一次登入該機械的時候，Bash照樣單調的色采，都沒變阿

接下來，就是功能參數了

於是決定下手點竄了Bash的PS1參數
