Okay. You can't insert variables inside strings like that because C is not a shell language. You have to create the string first, then call system with it. It's probably simplest to use sprintf.

Hello all !
Could someone throw some light on whether there's a limit to the number of characters contained in the command string that is passed to the system() call in C.
Is it OS dependent? If yes, what are the limits for each?
Thanks. (4 Replies)

doveadm-log
DOVEADM-LOG(1) Dovecot DOVEADM-LOG(1)NAME
doveadm-log - Locate, test or reopen Dovecot's log files
SYNOPSIS
doveadm [-Dv] log errors [-s min_timestamp]
doveadm [-Dv] log find [directory]
doveadm [-Dv] log reopen
doveadm [-Dv] log test
DESCRIPTION
The doveadm log commands are used to locate and reopen the log files of dovecot(1). It's also possible to test the configured targets of
the *log_path settings.
OPTIONS
Global doveadm(1) options:
-D Enables verbosity and debug messages.
-v Enables verbosity, including progress counter.
COMMANDS
log errors
doveadm log errors [-s min_timestamp]
The log errors command is used to show the last - up to 1,000 - errors and warnings. If no output is generated, no errors have occurred
since the last start.
-s min_timestamp
An integer value, representing seconds since the epoch - also known as Unix timestamp. When a min_timestamp was given, doveadm(1)
will only show errors occurred since that point in time.
log find
doveadm log find [directory]
The log find command is used to show the location of the log files, to which dovecot(1) sends its log messages. If dovecot(1) logs its
messages through syslogd(8) and doveadm(1) could not find any log files, you can specify the directory where your syslogd writes its log
files.
log reopen
doveadm log reopen
This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings. These settings
are configured in /etc/dovecot/conf.d/10-logging.conf.
This is for example useful after manually rotating the log files.
log test
doveadm log test
This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files. The used prior-
ities are: debug, info, warning, error and fatal.
EXAMPLE
This example shows how to locate the log files used by dovecot(1).
doveadm log find
Looking for log files from /var/log
Debug: /var/log/dovecot.debug
Info: /var/log/mail.log
Warning: /var/log/mail.log
Error: /var/log/mail.log
Fatal: /var/log/mail.log
