帮个忙,怎么自动检测文件更新,并做打印

liujuejun

tail -f prt.log|xargs -l1 prtfile1 & 不行啊
我试了下tail -f prt.log|prtfile1 也不行
我的prtfile1() 有两个参数一个是文件名 filename 一个是端口号 Is_tty
prtfile1()我试了没有问题
tail -f prt.log|prtfile1 &
echo "file1.txt ttyp1" >>prt.log
echo "file2.txt ttyp2" >>prt.log
filename 和 Is_tty 都是空值
望高手指点

tail -f 不实用,
我自己搞定了,自动备份文件,自动送空闲的打印机,经过测试,给大家参考(邮政代发农民补贴的有用)
需要建几个文件
WORKDWBH=dfgz/workdwbh
#DWBH单位编号 DWNAME 单位名称 XZBH乡镇编号 XZNMAE乡镇名 XZLEIBH发放类型编号 XZLEI
printf "43069042\t代发农民财政补贴\t001\t城郊乡\t003\t粮补\n" >workdwbh
REORTFILE=rpt${DWBH}
>prt43069042
PRTTTY=dfgz/log/prttty.log
#看你要增加多少端口
echo "tty01" >>prttty.log
DWFILE=dfgz/DWFILE.INI
printf "43069042\t430681016\t903021" >$DWFILE
正在要备份的报表文件在mid_sys/run/tmp/prj${单位编号}
找这行修改
