MySQL Syntax error with automated backup script
Hi guys,

I'm new to Linux and dont know much of scripting..there's an automated backup script that will backup the database from a location to another location between servers..it was created by another person and I tried to understand it somewhat..

I hope the script first checks if mount point is mounted and then starts backing up the database using From and To arguments..this script is to be added to crontab for daily backup..

I tried to run this script but it gives me syntax error...could someone please help me out with this..thanks in advance...Smilie

find $FromLoc -mtime -2 -type f -print | tar zcvf $TOLoc/"$FileName".tgz -T -

Almost certainly this script has been edited with a Microsoft editor such as Notepad rather than a unix editor such as "vi".
To prove this, please check the script file with the following "sed" command which is designed to make control codes visible.

Code:
sed -n l scriptname

A normal unix text file will display a "$" at the end of each line. A MS-DOS format file will contain "^M" characters.

hi...thanks for the help..I tried the "sed" command like u said and the result is as given below...

Quote:
[root@server]$ sed -n l backup_script.sh
#!/bin/bash\r$
#\r$
# creates backups of updated files for given day\r$
#\r$
# usage: backup_script.sh <from location> <to location>\r$
# eg: backup_script.sh /home/oracle /backup/server/database/\r$
# function DailyBackup()\r$
#Variable declaration\r$
FromLoc=$1\r$
TOLoc=$2\r$
FileName=D`date +%d`\r$
mnt_point=/nfs_backup/\r$
command=$(mount | grep $mnt_point | cut -d\\ -f3)\r$
{\r$
{\r$
if [ "$command" != "$mnt_point" ]\r$
then\r$
mount 122.23.1.12:/backup $mnt_point\r$
else\r$
echo "$mnt_point already mounted"\r$
fi\r$
}\r$
{\r$
find $FromLoc -mtime -2 -type f -print | tar zcvf $TOLoc/"$FileName\
".tgz -T -\r$
}\r$
}\r$
I normally use vi backup_script.sh to look up the file and use "i" to insert into it and quit with :x! to save the changes...

wat am i do next...pls help...

Yep. The ctrl-M (carriage-return) characters show as "\r".
This script file is in MS-DOS text file format not unix text file format.

What Operating System and version are you running? Most of them come with utilites to convert MS-DOS text files to unix format. Failing that there are ways to remove the carriage-return characters.


One fairly portable method is:
Code:
cat scriptname | tr -d "\032" | tr -d "\r" > newscriptname

This removes ctrl/Z (MS-DOS end-of-file) and ctrl/M (carriage return).

hi...

Its Red Hat Enterprise Linux ES release 4 (Nahant Update 2)

cat scriptname | tr -d "\032" | tr -d "\r" > newscriptname
I ran the script and got it conv to unix format...what is the other option to conv MSDOS file to unix format...

Will converting the script to unix format solve the problem or something else that I gotta do..

I'm trying to run the script now...will keep u posted..thanks for all the help..

any suggestions welcome...
