Untested but something like this:
find . -type f -exec sed -i 's/john/TOM/g' \{} \;
or
find . -type f | xargs sed -i 's/john/TOM/g' |

如果其中一个今天刚刚修改了，然后我想update everybody with newest version，怎
么弄？
批量删除倒是可以用：
$locate xxx > file
$xargs rm < file |

发帖数: 3195 | 5 the visiting programmer 有找master foo 这闲工夫，
不如把 unix command 的源程序都看一遍。
像什么 find, xargs, sort之类的，解释起来很费劲。
很多书费了半天劲，举了若干垃圾例子，还是讲不清楚。
源代码看一下其实很简单。 |

发帖数: 1212 | 7 不要用python，用awk就够啦！awk是linux里处理csv,tsv之类的最好最方便的工具，不
用费力气去写python程序。google一下awk的wiki就知道怎么用了。
另外你的文件很大，我猜测你用的是多CPU的linux服务器。这种情况下并行处理可能会
更快一些。我知道的办法是split成小文件以后，ls|xargs awk...|cat 再加并行的参
数 （好像是-P）之后可以合并结果文件。

If in NT, why not do a search for '*.d' and '*.o' files, and
delete them in the result window? |

发帖数: 182 | 17 Directly copying stuff over would probably not work.
You will run into similar dynamic link problems.
That said, to find a file foo, and look for string bar iin
it,
you do
find /usr -name foo -print | xargs grep bar |

Try to see if "sed" can help:
sed -i'.bak' -e 's/^\([^\/]*\)\/\{2,\}\(.*\)$/\1\/*\2*\//g'filename.c
Above command will repalce "//..." to "/*...*/" in filename.c (and make a
backup of "filename.c" named "filename.c.bak").
To replace all files, use "find" and "sed" together:
find -iname '*.c' -print0 | xargs -0 sed -i'.bak' -e
's/^\([^\/]*\)\/\{2,\}\(.*\)$/\1\/*\2*\//g' |
