svn: Can't open file ' . --revision/format': No such file or directory

[prashant n]

Hi ALL,

i am encountering the above error ie, svn: Can't open file ' . --revision/format': No such file or directory , when i try to backup my svn repo daily thru a script. The script is as follow:

#!/usr/bin/perl -w
#
# Perform a daily backup of a Subversion repository,
# using the previous most-recently-backed-up revision
# to create just an incremental dump.
#use strict;
#use warnings;
my $svn_repos = "/cvs/satrang/software";
my $backups_dir = "/home/svnbkp";
my $next_backup_file = "daily-incremental-backup." . `date +%Y%m%d`;
#print "*$next_backup_file*\n";
open(IN, "$backups_dir/last_backed_up");
$previous_youngest = <IN>;
chomp $previous_youngest;
close IN;
my $youngest = `svnlook youngest $svn_repos`;
chomp $youngest;
if($youngest eq $previous_youngest) {
print "No new revisions to back up.\n";
exit 0;
}
# We need to backup from the last backed up revision
# to the latest (youngest) revision in the repository
$first_rev = $previous_youngest + 1;
$last_rev = $youngest;
print "\n....Backing up revisions $first_rev to $last_rev...\n";
$svnadmin_cmd =`svnadmin dump --incremental " . "--revision $first_rev:$last_rev ". "$svn_repos > $backups_dir/$next_backup_file`;
`$svnadmin_cmd`;
print "\n...Compressing dump file...\n";
print `gzip -9 $backups_dir/$next_backup_file`;
open LOG, ">$backups_dir/last_backed_up";
print LOG $last_rev;
close LOG;

How to overcome this error?
Regards
Shann

$svnadmin_cmd =`svnadmin dump --incremental " . "--revision
$first_rev:$last_rev ". "$svn_repos > $backups_dir/$next_backup_file`;

How about changing those backquotes to regular double quotes.

$svnadmin_cmd = "svnadmin dump --incremental " . "--revision
$first_rev:$last_rev ". "$svn_repos > $backups_dir/$next_backup_file";

Hi ALL,
i am encountering the above error ie, svn: Can't open file '
. --revision/format': No such file or directory , when i try to backup
my svn repo daily thru a script.

The book says that the switches, like --revision, must come after the
repository name, not before. Nasty... modern practice is for switches
to be accepted anywhere, and older practice is for switches to come
first, not last, so this is rather confusing.

But it seems to explain the message -- it looks like the program is
trying to interpret "--revision" as the repository name.
