grep 在HP-UX下的递归查找
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
grep 在HP-UX下的遞歸查找
Linux: man grep 可以看到 -r 選項
?-R, -r, --recursive
????????????? Read all files under each directory, recursively; this is equivalent to the -d recurse option.
即:-r 選項可以查找指定目錄下每個子目錄下的所有文件
eg:
grep -r "28281" .
//查詢當前路徑下文件及各個子目錄下的所有文件中的包含28281的文件;
但是在HP-UX下不支持-r這一選項,怎么辦呢?
查詢man find,可以看到:
?-exec cmd??????????????? True if the executed cmd returns a zero value
?????????????????????????????? as exit status.? The end of cmd must be
?????????????????????????????? punctuated by a semicolon (;) or a plus sign
?????????????????????????????? (+) (semicolon and plus are special to the
?????????????????????????????? shell and must be escaped).? When + is used,
?????????????????????????????? cmd aggregates a set of path names and
?????????????????????????????? executes on the set.? Any command arguments
?????????????????????????????? between the first occurrence of {} and + are
?????????????????????????????? ignored.? The reason for preferring + to a ;
?????????????????????????????? is vastly improved performance.? Any command
?????????????????????????????? argument {} is replaced by the current path
?????????????????????????????? name.? cmd may contain supplementary code set
?????????????????????????????? characters.
?????????????????????????????? // 命令必須以分號;或者加號+結束(分號和加號在shell
?????????????????????????????? 中有特殊意義,必須用轉義)。當使用+時,命令會聚集成
?????????????????????????????? 路徑名的一個集合,{}和+之間命令參數會被忽略。
?????????????????????????????? 優先使用+,是因為+的性能更好。
?????????????????????????????? 命令中的參數{}將會被當前的路徑名說取代。
比如:
find . -type f -exec grep "IFPC" {} \+
//在當前路進行及其子文件夾中的文件中查找包含IFPC字符串的文件;
