在linux中怎样在一个文档中查找一个字符串呢?
出现以下错误:
[root@proserver bandwidthd-1.2.1b]# sed -i's/top20/top100/g'graph.c
sed: invalid option -- i
Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file]...
-n, --quiet, --silent
suppress automatic printing of pattern space
-e script, --expression=script
add the script to the commands to be executed
-f script-file, --file=script-file
add the contents of script-file to the commands to be e
--help display this help and exit
-V, --version output version information and exit
If no -e, --expression, -f, or --file option is given, then the first
non-option argument is taken as the sed script to interpret. All
remaining arguments are names of input files; if no input files are
specified, then the standard input is read.

Be sure to include the word ``sed'' somewhere in the ``Subject:'' field.
