mysqldump --tab: file already exists when it does not

This is all on one server.

mysqldump -u root -p --tab=/var/tmp --fields-terminated-by=, db1

mysqldump: Got error: 1086: "File '/var/tmp/db1_tbl.txt' already exists" when executing 'SELECT INTO OUTFILE'

Strange. But the file doesn't exist?

ls /var/tmp/db* /var/tmp/db1_tbl.sql

No .txt file? Where is the delimited text file?

I am on CentOS 7:

mysql Ver 15.1 Distrib 5.5.52-MariaDB, for Linux (x86_64) using readline 5.1

I understand this outputs to the server host. But I am running this command from the server.

Please provide below information to solve this issue :- 1) Provide all the steps you have performed 2) output of below commands: a) getenforce b) ls -ldZ /var/tmp/ [to check context type]

3) Have you changed the context type of directory /var/tmp by below command in case SElinux checked by getenforce command is "enforcing" a) semanage fcontext -a -t mysqld_db_t "/var/tmp(/.*)?" b) restorecon -vR /var/tmp/
