问题描述
我正在尝试从我的 users 数据库备份我的 cia 表
我已经创建了这个示例片段
示例
#db = cia
#table = users
MysqLdump cia users > cia.users.sql && L <<-------- ✅
MysqL -u root cia -e "TruncATE TABLE users;" <<-------- ✅
MysqL -u root cia -e "SELECT COUNT(*) FROM users;" <<-------- ✅
MysqL -u root cia users < cia.users.sql <<-------- ?❌ stuck...
MysqL -u root cia -e "SELECT COUNT(*) FROM users;"
rm -rf cia.users.sql
echo "--------------------------- DONE."

Usage: MysqL [OPTIONS] [database]
-?,--help display this help and exit.
-I,--help Synonym for -?
--auto-rehash Enable automatic rehashing. One doesn't need to use
'rehash' to get table and field completion,but startup
and reconnecting may take a longer time. disable with
--disable-auto-rehash.
(Defaults to on; use --skip-auto-rehash to disable.)
-A,--no-auto-rehash
No automatic rehashing. One has to use 'rehash' to get
table and field completion. This gives a quicker start of
MysqL and disables rehashing on reconnect.
--auto-vertical-output
Automatically switch to vertical output mode if the
result is wider than the terminal width.
-B,--batch Don't use history file. disable interactive behavior.
(Enables --silent.)
--bind-address=name IP address to bind to.
--binary-as-hex Print binary data as hex. Enabled by default for
interactive terminals.

Directory for character set files.
--column-type-info display column type information.
-c,--comments Preserve comments. Send comments to the server. The
default is --skip-comments (discard comments),enable
with --comments.

--histignore=name A colon-separated list of patterns to keep statements
from getting logged into syslog and MysqL history.
-G,--named-commands
Enable named commands. Named commands mean this program's
internal commands; see MysqL> help . When enabled,the
named commands can be used from any line of the query,otherwise only from the first line,before an enter.
disable with --disable-named-commands. This option is
disabled by default.

-o,--one-database Ignore statements except those that occur while the
default database is the one named at the command line.
--pager[=name] Pager to use to display results. If you don't supply an
option,the default pager is taken from your ENV variable
PAGER. Valid pagers are less,more,cat [> filename],etc. See interactive help (\h) also. This option does not
work in batch mode. disable with --disable-pager. This
option is disabled by default.
-p,--password[=name]
Password to use when connecting to server. If password is
not given it's asked from the tty.
-P,--port=# Port number to use for connection or 0 for default to,in
order of preference,my.cnf,$MysqL_TCP_PORT,/etc/services,built-in default (3306).
--prompt=name Set the MysqL prompt to this value.
--protocol=name The protocol to use for connection (tcp,socket,pipe,memory).
-q,--quick Don't cache result,print it row by row. This may slow

--connect-timeout=# Number of seconds before connection timeout.
--max-allowed-packet=#
The maximum packet length to send to or receive from
server.
--net-buffer-length=#

commands depends on the patterns supplied via histignore
option besides the default patterns.
--plugin-dir=name Directory for client-side plugins.
--default-auth=name Default authentication client-side plugin to use.
--binary-mode By default,ASCII '\0' is disallowed and '\r\n' is
translated to '\n'. This switch turns off both features,and also turns off parsing of all clientcommands except

piped to MysqL or loaded using the 'source' command).
This is necessary when processing output from MysqLbinlog
that may contain blobs.

expired password sandBox mode.
--network-namespace=name
Network namespace to use for connection via tcp with a
server.

Use compression algorithm in server/client protocol.
Valid values are any combination of
'zstd','zlib','uncompressed'.

Use this compression level in the client/server protocol,in case --compression-algorithms=zstd. Valid range is
between 1 and 22,inclusive. Default is 3.
--load-data-local-dir=name
Directory path safe for LOAD DATA LOCAL INFILE to read
from.
Default options are read from the following files in the given order:
/etc/my.cnf /etc/MysqL/my.cnf ~/.my.cnf
The following groups are read: MysqL client
The following options may be given as the first argument:
--print-defaults Print the program argument list and exit.
--no-defaults Don't read default options from any option file,except for login file.
--defaults-file=# Only read default options from the given file #.

--defaults-group-suffix=#
Also read groups with concat(group,suffix)
--login-path=# Read this path from the login file.

解决方法
mysql 客户端接受一个数据库名称，但不需要在该命令行用法中命名表。表的名称来自转储数据文件中的语句。
改变这个：
mysql -u root cia users < cia.users.sql
为此：
mysql -u root cia < cia.users.sql
