  awk '{print substr($0, 0, 200)}' data.log | tail -20

2: awk 分割字符串
  echo '1234qw212' | awk -F 'qw' '{print $1 "-" $2}'
  1234-212

3: 按照文件每行长度排序
tset.txt
qwe
ewewew
qw
dedefefe
 
awk '{print $1 ":" length($1)}' test.txt | sort -n -t : -k 2 | awk -F ":" '{print $1}'
 
输出:
qw
qwe
ewewew
dedefefe

alias clt=cleartrash
trash()

}
