这个语法有什么问题？ 如何直接在远程FTP上写输出，因为硬盘空间不足？
该命令正在工作，但没有硬盘空间来获得完整的结果：
find /somedir/ -name '*.*' -exec grep -i 'some string' /dev/null {} + >> /somedir/output.txt 我试过类似的东西，但我得到错误“操作不适用”：
find /somedir/ -name '*.*' -exec grep -i 'some string' /dev/null {} + >> ftp -u ftp://[email protected] /somedir/output.txt
grep -r 'some sting' /somedir | ssh user@host "dd of=outputfile"
这可能会诀窍，如果你可以使用ssh而不是ftp。
我这样做，我不知道这是否更明确的方式。
#! /usr/bin/perl -w use Net::FTP; open(TMPOUT, ">>","/tmp/tmpout.txt"); *STDOUT = *TMPOUT; ### Redirect STDOUT to /tmp/tmpout.txt #select TMPOUT; my ($ftp, $host, $user, $pass, $dir, $fpath); $host = "localhost"; $user = "myftpuser"; $pass = "myftppassword"; $dir = "/tmp"; $ftp = Net::FTP->new($host, Debug => 0); $ftp->login($user, $pass) || die $ftp->message; $ftp->cwd($dir); while(<STDIN>) { print $_ . "\n"; } ####Printing the STDING to /tmp/tmpout.txt $ftp->append("/tmp/tmpout.txt", "myremoteout.txt"); ### Now i append the oupout of the local file /tmp/tmpout.txt to the remote ftp file /tmp/myremoteout.txt $ftp->quit;
现在chmod +x f.pl并find / -type f | ./f.pl find / -type f | ./f.pl
在ftp服务器上输出grep "^/" /tmp/myremoteout.txt ：
