私はexpファイルを実行しようとします:
#!/usr/bin/expect
# mysql credentials and connection data
current_db_name='webui_dev'
new_db_name='db_2013'
db_host='localhost'
db_user='root'
db_pass=''
# using a here-document to pass commands to expect.
# (the commands could be stored in a file as well)
expect <<EOF
log_user 0
spawn mysqldump -h "$db_host" -u "$db_user" -p "$current_db_name" | mysql -h "$db_host" -u "$db_user" -p "$new_db_name"
expect "password:"
send "$db_pass\r"
log_user 1
expect eof
EOF
-f
フラグを付けて if を実行すると、エラーが発生します。mysqldump: Couldn't find table: "|"
このアプローチを試してみると
exp_internal 1
spawn sh -c "mysqldump -h \"$db_host\" -u \"$db_user\" -p \"$current_db_name\" | mysql -h \"$db_host\" -u \"$db_user\" -p \"$new_db_name\" "
