【问题描述】:
我一直在尝试通过 SSH 远程命令访问时进行循环工作,但它不起作用。该命令在主机中直接运行时有效。
scp file root@${SERVER}:/tmp
ssh ${SERVER} "
while IFS= read -r line; do
echo "$line"
done </tmp/file
"
我曾尝试在主脚本中使用单引号,但它会导致错误。
bash: line n: warning: here-document at line n delimited by end-of-file
任何建议将不胜感激。

脚本测试

ssh ${SERVER} '
echo "inside remote ClientServer"
echo "cat testfile"
cat /tmp/testfile
while read line; do
echo "${line}"
done <</tmp/testfile
'
echo "Back to MasterServer..."
终端结果
