Top Forums UNIX for Beginners Questions & Answers Expand Variables and Wildcards into another variable. Post 303035165 by MadeInGermany on Wednesday 15th of May 2019 02:32:39 PM

You see the difference with
Code:
echo "$file_path"

The quotes prevent the shell to do word-splitting on command arguments.

ls is an external command. The efficient per-line formatter is printf "%s\n" that 1. is a shell-builtin and 2. does no extra I/O.

What do you want to do with the $file_path?
It can make sense to not expand it too early. For example
Code:
file_path="${output_dir}/*MIGRATE*${city_name}*.out"
for f in $file_path

is smarter than
Code:
file_path=`ls ${output_dir}/*MIGRATE*${city_name}*.out`
for f in $file_path

radsqlrelay [-?] [-d sql_driver] [-b database] [-f file] [-h host] [-u user] [-P port] [-p password] [-1] [-x] file_path DESCRIPTION
radsqlrelay tails a SQL logfile and forwards the queries to a database server. Used to replicate accounting records to one (central) data- base, even if the database has extended downtime. The SQL logfile is created by the rlm_sql_log module. The module must be configured in the radiusd server before you can use radsqlrelay. OPTIONS
-? Print usage help information. -d sql_driver Driver to use: mysql, pg, oracle. -b database Name of the database to use. -f file Read password from file, instead of command line. -h host Connect to host. -u user User for login. -P port Port number to use for connection. -p password Password to use when connecting to server. -1 One-shot mode: push the file to database and exit. -x Turn on debugging. file_path The pathname of the SQL logfile to use. NOTES
Oracle driver The command "radsqlrelay -d oracle -b db.domain.tld sql-relay" reads the database description stored in $TNS_ADMIN/tnsnames.ora: db.domain.tld = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = db.domain.tld)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = <DB SID>) ) ) SEE ALSO
