我想处理一个文件，先匹配到第某一行如第2行，然后修改从这行往下面数的第3行.用awk怎么处理?我试了下面的语句，好像不行，FCDF被重写了为何改不了第3行？ # cat ttt.txt FIRST BEST BEST2 # awk 'BEGIN{print "-----Begin"} {if(/BEST/){FF=NR+1;print FF} if(NR==FF)print "test"} END{print "-----END"}' ttt.txt -----Begin 3 4 -----END

刚才发了个帖子没把问题说清楚还是没解决 for FI in $FILENAME do awk -f '[ ]' '{print $FI, $1,$2}' $FI>> myfile done 我想把文件名写到myfile的每一行的前面但是awk中好像已经不识别FI了，请问怎么才能再awk中用awk外定义的变量呢？
