Shell Script notes (the original is constantly recorded)

Start your own shell script practice today, just as the company has too servers, to time the data of the CP is monthly:

Consider: First look for the law, found all placed in the/opt/www/aaa/there are a lot of 2 level and 3 levels of directories and files, but I track to back up is the date of the year as the file name format: 2015_06

In this format, first we don't know how many of these 2015_06 subdirectories are in this directory so we need to count:

Find/opt/www/aaa-name 2015_06 Look at the place I want to back up #!/bi#admin fengtaotao Email:23956580@ Qq.com

#Fri Jul3  -: *: -Cst -Pathh=/opt/www/acc/musicfile/@ First defined is the source file pathPATHD=/opt2/musicfile/@ The path to be backed upDatem=`Date+%m ' @ Here I define a display reason for the current month is that I am in crontab to back up is the last month's #getmonth @ simple Comment I like it. Comments are written under the line code if ["$datem" = =];th En @ Current month is January so current year-1 thereby back up last year's December
datem= "_12" @ If the current month is January then the stiffness variable is modified to December
datey= ' Date +%y '
datey=$ (($datey-1)) @ Change the year to last year it was last December.
Else
Datem= "_0$ (($datem-1))" Datey=`Date+%Y ' @ Considering the January of the year to back up last year's fi
#getFullYear

Dird="$datey $datem"#Echo "$dird"Readd=`Date+%N '. txtFind$pathh-name $dird &>>$readd forIinch$(Cat$readd); DoAAC=$(Echo$i |awk-F"/" '{print $6 "/" $7 "/"}') AAC=${PATHD}${AAC}CP-R $i $AAC &>> dbcp. Log DoneRM-RF $readd

OK Next Modify the permissions and the timing of the crontab

chmod u+x dbback. SH  -e011 * */root/bash/dbback. SH No. 1th in the month. 1 o'clock in the morning start backup

2. Of course I also wrote a manual backup script

#!/bin/bash#admin Fengtaotao Email:23956580@qq. Com#fri Jul3  -: *: -Cst -Pathh=/opt/www/morp/musicfile/PATHD=/opt2/musicfile/TouchUlist.txtreadd=Ulist.txt forAinch$(CatList.txt); Do    Find$pathh-name $a &>>$readd Done forIinch$(Cat$readd); DoAAC=$(Echo$i |awk-F"/" '{print $6 "/" $7 "/"}') AAC=${PATHD}${AAC}CP-R $i $aac &>>Dbcp.log DoneRM-RF $readd

We can create a list.txt document in the same directory as the script, and write a list of names that we need to back up. The default is to change the behavior by a name
