Perl 食谱 7.18 #!/usr/bin/perl open OUTPUT,"| tee -a out.log" or die $!; print OUTPUT "Hello to out.log and stdout\n"; open OUTPUT1,"| tee -a out.log out2.log >/dev/null" or die $!; print OUTPUT1 "Hello to out.log and out2.log\n"; adolf@master:/tmp$ ./tee.pl Hello to out.log and stdout adolf@master:/tmp$ cat out.log Hello to out.log and stdout Hello to out.log and out2.log adolf@master:/tmp$ cat out2.log Hello to out.log and out2.log 解说 open 後面档名有个 | 表示打开一个pipe到 tee这只程式 之後perl的output就会传给tee当input 然後就让tee去烦恼了... -a表示tee会append...不然第二次的时候out.log就会被truncate.. 低阶io应该也有不用到tee的办法...只是要找找... --
