sort file by length of lines

sort file by length of lines
按每行长度对文件内容排序

比如文件包含一些人名, 想按名称长度进行排序

cat >myfile <<EOF

Andrew Mogrelia
Antonio Vivaldi
Antoni Wit
Capella Istropolitana
Christian Kohn

EOF

awk得到每行的长度, 按长度排序后显示输出

awk '{print length,$0}' myfile|sort -rn|cut -d" " -f2-

或者将管道写在print后
awk '{print length,$0|"sort -rn|cut -d\" \" -f2-"}' myfile

运行结果
