如何在文件中使用 sed 命令刪除模式？
我有一個文件，我想刪除所有模式，以便我只保留一些資訊，即該文件的製作者/創建者。
我設法用一個單詞“PATTERN”替換了模式，以便輕鬆刪除它們。我怎樣才能刪除這個詞？以下是我使用的命令：
$ cat /path | tr \n \f | \ tr -cd "[A-Za-z0-9 () /\f] | \ sed s/stream.*endstream/STREAM/ | sed s/[0-9][0-9]* /PATTERN/g | \ sed "s/PATTERN PATTERN n/PTR/g"我得到這個

如何去掉PATTERN這個詞？
嘗試以下操作：
sed -i -e 's/PATTERN//g' filename
