如何在shell脚本中存储IP地址？

Question

I want to scp a file from a remote machine to my machine using a shell script:

SRC_PASS="pass" 
SRC_PORT="22" 
SRC_USER="root" 
SRC_IP="x.x.x.x"
TAR_SRC="/tmp/abc.gz" 

echo $SRC_IP 
sshpass -p $SRC_PASS scp -P $SRC_PORT $SRC_USER@$SRC_IP:$TAR_SRC /tmp/xy.gz

I have debugged and found out that the $SRC_IP for some reason isn't storing the IP address properly.

For example, it works if I use this:

sshpass -p $SRC_PASS scp -P $SRC_PORT $SRC_USER@x.x.x.x:$TAR_SRC /tmp/xy.gz

I believe you need to enclose your variable names in curly braces so the shell does not consider "@" or ":" as part of the variable name. Example:

sshpass -p $SRC_PASS scp -P $SRC_PORT ${SRC_USER}@${SRC_IP}:${TAR_SRC} /tmp/xy.gz

If that's not the issue and the script is in bash, use

bash -x /path/to/script.txt

To execute it and see the issue.
