Shell脚本分割文件成相同行数的文件

使用shell脚本将testfile.txt文件（共7800行）分割成13个文件，每个文件600行，文件名的前缀是SplitFile[root@www.linuxidc.com /home/sysadmin/zhaoyj]# cat testfile.txt |wc -l
    7800脚本如下：[root@www.linuxidc.com /home/sysadmin/zhaoyj]# cat split.sh #！/bin/sh
linenum=`wc -l testfile.txt |awk "{print $1}"`
Num1=1
FileNum=1
while [ $Num1 -lt $linenum ]
do
                Num2=`expr   $Num1   +   599`
                sed   -n   "${Num1},   ${Num2}p "   testfile.txt   >   SplitFile$FileNum
                Num1=`expr   $Num2   +   1`
                FileNum=`expr   $FileNum   +   1`done  最后生成的文件是[root@www.linuxidc.com /home/sysadmin/zhaoyj]# ls |grep "^SplitFile" |wc -l
      13[root@www.linuxidc.com /home/sysadmin/zhaoyj]# ls |grep "^SplitFile"       SplitFile1
SplitFile10
SplitFile11
SplitFile12
SplitFile13
SplitFile2
SplitFile3
SplitFile4
SplitFile5
SplitFile6
SplitFile7
SplitFile8
SplitFile9 最后再核实一下每个文件的大小是否一致[root@www.linuxidc.com /home/sysadmin/zhaoyj]# ls |grep "^SplitFile" |xargs wc -l
