So let’s look at fixing this.

  1. Launch BonEcho / Firefox and enter about:config into the address bar.
  2. You’ll get a “page” that consists of row upon row of preferences. Right-click / control + click anywhere on the page. Select New and then from the sub-menu select String.
  3. A sheet appears asking for a New string value. Entergeneral.useragent.override and click OK or hit return.
  4. Another sheet appears asking for you to Enter string value. This is where you enter the user agent BonEcho / Firefox should use to identify itself to servers.

rename 이라는 명령을 사용하면 됩니다.

rename aaa bbb *.c

확장자가 c 인 파일이름 중 aaa 가 있는 경우에 그 부분을 bbb로 치환하여 파일이름을 바꾸어 줍니다.

xaaax.c -> xbbbx.c

예) 현재 폴더 아래의 모든 html 파일의 확장자를 php로 변경

find . -name "*.html" | xargs rename .html .php
