谢了！

Normally, it is convenient to use sed to replace patterns in one file. For instance:
sed \'s/abc/xyz/\' file1 >;file1.out  ( you can replace \'abc\' with \'xyz\' in file1)

Sometime, \'awk\' can be used to do replacement too.
For instance:
awk \'$1==\"abc\"{$1=xyz}\' file1 >; file1.out

See manuals of \'sed\' and \'awk\' for detail.
They are actually two interesting and useful program lanuages.

谢谢albert,hpux！
补充一下，第一句好像应该改为 sed \'s/abc/xyz/g\' file1>;file1.out
另外，我的解决方法与你不一样，麻烦了点：
cat - << EOF | ed -s /tmp/file1
           1,$ s/\"abc/xyz/g
           w /tmp/file1.new
           q
           EOF
