python - shell脚本查找字符串并递归打印当前行和下一行

Question

我编写了一个小脚本，用于搜索字符串并打印当前行。但我对打印下一行有点困惑。我对 bash/perl/python 没问题

#!/bin/bash  

CURRENT_DIR=`pwd`
cnt=0

for dir in $(find $CURRENT_DIR -type d)
do
    for myFile in $dir/*  
    do 
        if [ -f "$myFile" ]; then
            cat $myFile | while myLine=`line`
            do
                allFile="$myLine"    
                if echo "$myLine" | grep -q $1 ; then 
                    echo "$myFile" "$allFile" ""
                fi  
                #echo 'expr $count+1'
                #echo   "$allFile"   ""
            done #LINE  
        fi
    done #FILE
done # DIRECTORY

如果您的 grep 是 GNU:

 grep -A1 pattern file
