Backup MYSQL Database
#!/bin/bash mdate=`date +%F` echo "================ backing up databasename database ==============" mysqldump -u username -ppassword databasename > databasename-$mdate.sql sleep 5 echo "================ backing up databasename ====================" mysqldump -u username -ppassword databasename > databasename-$mdate.sql sleep 5 echo "=============== Backing up databasename database =============" mysqldump -u username -ppassword databasename > databasename-$mdate.sql sleep 5 echo " ========= done =========" ls *.sql > /var/www/sqlfiles.txt sleep 5 # calls another script which does the actual backup to amazon cd /var/dirtoscripts/ ./bksql.sh
Backup HTML Directory
#!/bin/bash bkdate = `date +%F` cd /var/www/ sleep 1 filename=outwaterphotogallery-$bkdate.zip #zip html folder zip -r $filename /var/www/html sleep 5 if [ "$filename" ]; then aws s3 cp --region us-east-1 $filename s3://websitebackup-opi/web/ fi sleep 4 count=`ls -l *.zip | wc -l 2> /dev/null` if [ $count -ge 1 ]; then mv *.zip /var/www/backups/web/ fi
Script that backs up to Amazon S3
#!/bin/bash echo "--------- backing up to s3 --------------" set -e if [ -f sqlfiles.txt ]; then while read line do aws s3 cp --region us-east-1 $line s3://bucketname done < sqlfiles.txt echo "++++++++++= Done =+++++++++++++++" else echo " XXXXXXXXXXX File Does not exist XXXXXXX" fi cd /var/www/dirtoscripts/ # call script that counts the num of sql files in dir and move them to an archive folder ./cleanupscript
Find files and rsync them to a dir
find . -type f -name '*.jpg' -exec rsync -zavhP {} /dirctorytocopyto/ \;
Find Multiple filenames
find . -type f \( -name "*.nef" -o -name "*.jpg" -o -name "*.tif" \)
RSYNC copy directories with spaces
find . -type f -name '*177*' -exec rsync -zavP {} "/var/tmp/my dir" \;
Count Files in Directory
cd /var/www/
count=`ls-l *.sh | wc -l 2> /dev/null` if [ $count -ge 1 ]; then mv *.sql /var/www/backups/dirname fi
Find and delete files with certain names
find -type -f -name '*one*' -exec rm {} \;
Find files x days old and delete them
#!/bin/bash
find /path/to/files/ -type f -name '*.jpg' -mtime +10 -exec mv {} /path/to/archive/ \;
find /path/to/archive/ -type f -name '*.jpg' -mtime +30 -exec rm {} \;
- First part is the path where your files are located. Don’t use wildcard * if you have a lot of files because you will get Argument list too long error.
- Second part -type is the file type f stands for files
- Third part -name is limiting *,jpg files
- Fourth part -mtime gets how many days the files older than will be listed. +30 is for files older then 30 days.
- Fifth part -exec executes a command. In this case mv is the command, {} gets the filelist, path where to move the files and \; closes the command
Find files over a certain size
$ find . -type f -size -4G
You can use size switch for other formats, such as
- `c’ for bytes
- ‘w’ for two-byte words
- `k’ for Kilobytes
- `M’ for Megabytes
- `G’ for Gigabytes
Find Directory sizes
du -h --max-depth=2 | sort -hr
