linux - mkdir : missing operand - ssh -tt ${REMOTE_SERVER} sudo sh -c "mkdir -p/opt/migration"

Question

给定:

MIGRATION_FOLDER=/opt/migration

要么这样:

ssh -tt ${REMOTE_SERVER} sudo sh -c "mkdir -p /opt/migration"

或者这个:

ssh -tt ${REMOTE_SERVER} sudo sh -c "mkdir -p '$MIGRATION_FOLDER'"

返回:

mkdir: missing operand

感谢帮助。

Answer 1

您需要额外的报价。

ssh -tt ${REMOTE_SERVER} sudo sh -c "'mkdir -p \"$MIGRATION_FOLDER\"'"

或:

ssh -tt ${REMOTE_SERVER} "sudo sh -c 'mkdir -p \"$MIGRATION_FOLDER\"'"

如果您需要执行多个命令，请将它们全部放在单引号内。

ssh -tt ${REMOTE_SERVER} "sudo sh -c 'rm -rf \"$MIGRATION_FOLDER\"; mkdir -p \"$MIGRATION_FOLDER\"'"
