ksh以特定语句回显stderr

Question

我有以下shell脚本,回声输出到日志和错误到err_file.但是,我特别希望向stderr回应一些陈述.请帮忙

#!/bin/ksh
echo "paramPassed: $0 $#" 

err_file="error_file.txt"
new_file="new_file.txt"

exec >> ${new_file}
#exec >> ${new_file} 2>${err_file}
#exec >> ${new_file} 2>&1

if [ $# -eq 1 ]; then
    username=$1
fi  

userInfo=$(paramInfo ${username} | awk -F: '{print $2}')
echo ${userInfo} 

rcp ${err_file} mtvst32:/rcs/ver34/${err_file}

if [ $? -ne 0 ]; then
        #This doesn't work. Need the following to go to console
        echo "UserInfo.SH FAILED copy to mtvst32" >> &2; 
fi  

我希望将最后一个if条件的输出发送到std err但是,无法弄清楚该怎么做.

Answer 1

我怀疑你收到了一条错误信息.如果您发布它会有所帮助.但是,这可能会解决您的问题:

echo "UserInfo.SH FAILED copy to mtvst32" >&2
