我想实现这样的操作.
对一个文件做统计,统计出文件里的最大和最小所在行.

文件描述:
a0003b
c0002d
f0005d
f0006v
a0004t
......
......
这文件每列2到5的字符是有序的数值,其他字符无序

预期结果是返回最大值所在的记录行:f0006v, 最小值所在的记录行c0002d

Shell代码 


1. root [ ~/fnz ]0# grep `sed -e 's/^.//' data | sort | head -n 1` data   
2. c0002d   
3. root [ ~/fnz ]0# grep `sed -e 's/^.//' data | sort | tail -n 1` data   
4. f0006v   
5. root [ ~/fnz ]0#  
 
root [ ~/fnz ]0# grep `sed -e 's/^.//' data | sort | head -n 1` data
c0002d
root [ ~/fnz ]0# grep `sed -e 's/^.//' data | sort | tail -n 1` data
f0006v
root [ ~/fnz ]0#

1. root [ ~/fnz ]0# sort -k1.2,5 data | sed -n '1p;$p'
2. c0002d   
3. f0006v   
4. root [ ~/fnz ]0#  
 
root [ ~/fnz ]0# sort -k1.2,5 data | sed -n '1p;$p'
c0002d
