How to delete content of a log file from linux terminal?
提问by Sushan Ghimire
I have a log file on server called writelogwhich is about 2GB.
我呼吁服务器日志文件writelog大约是2GB。
I want to delete first 100,000lines from the file. I could open the file and delete those lines but because of the file size it takes me forever to download it.
我想100,000从文件中删除第一行。我可以打开文件并删除这些行，但由于文件大小，我需要永远下载它。
