这种问题自己试一下不就知道了,还是用前面贴的代码示例:
[root@RHEL6A shcode]# ./sh25.sh >> mylog2.txt [root@RHEL6A shcode]# ls config mylog.txt sh12.sh sh15.sh sh18.sh sh21.sh sh24.sh temp.sh ftpautologin.sh nohup.out sh13.sh sh16.sh sh19.sh sh22.sh sh25.sh mylog2.txt sh11.sh sh14.sh sh17.sh sh20.sh sh23.sh sleep.sh [root@RHEL6A shcode]# cat mylog.txt hello ls: cannot access aaabbbccc: No such file or directory [root@RHEL6A shcode]# cat mylog2.txt [root@RHEL6A shcode]#
