一個替換文字檔中某一個關鍵字附近的某一行的某一段的shell程式：__開發

一個替換文字檔中某一個關鍵字附近的某一行的某一段的shell程式：

#!/bin/bashfile=$1findpattern=$2linegap=$3replacepattern=$4substitue=$5help(){  echo help:  echo \$1:file\'s full path \(include filename\)  echo \$2:the key string to be find  echo \$3:the line count between the line where key string in and the line to be modified  echo \$4:the string to be replace  echo \$5:the string will take place the key string}echoinput(){  echo \$1=$file  echo \$2=$findpattern  echo \$3=$linegap  echo \$4=$replacepattern  echo \$5=$substitue}if [ "$5" == "" ];then  help;  exit -1;fiechoinput;if [ ! -f ${file} ];then  echo $file is not exist.fi#echo "awk '/${findpattern}/{print NR}' ${file}";n=`awk '/'"${findpattern}"'/{print NR}' ${file}`;if [ "$n" == "" ];then  echo can not find ${findpattern} in ${file};  exit -1;fiecho find key string in line $n;if [ ! -n $n ];then  echo find too much lines.  exit -1;fin2=`expr $n + ${linegap}`;echo will modify line $n2,line contnet is:;awk 'NR=='${n2}'{print $0}' ${file};#echo "sed ${n2}'s/${replacepattern}/${substitue}/g' ${file} > tmp${file};"sed ${n2}'s/'"${replacepattern}"'/'"${substitue}"'/g' ${file} > tmp${file};diff ${file} tmp${file}

還有些bug：只能在文字檔目前的目錄下運行。不修改了。
