Help with Linux Shell Script

Some programs don't like to have their log files yanked out from under them.  Some will stop logging, and some will continue to log to the same file even if it moves instead of creating a new file.  Usually restarting the service after moving a log file is a good idea (or stop, move file, then start).

All systems either have logrotate installed on them or available as an option.  You might want to take a look at this - it provides a nice framework for backing up files on a date or size basis, compressing them, keeping X days worth, and also lets you do things before and after you back up the files (like stop or start a service).

#/bin/bash
mytmp="/tmp/"`date +'%d%m%Y%'`
mkdir $mytmp
cp -r  /lun3local/LOGS/Bla/*  $mytmp
[root@node1 lun3local]#


i got error 31032008%??

why with ?????

mytmp="/tmp/"`date +'%d%m%Y%'` there is a % too much!

mytmp="/tmp/"`date +'%d%m%Y'` is the right one, you may try by typing in the shell:

[root@node1 lun3local]# date +'%d%m%Y

i forgot also to tell, if  /LOGS/Bla/* have a subdirectory you should you
cp -r  /LOGS/Bla/* $mytmp

#/bin/bash
mytmp="/tmp/"`date +'%d%m%Y'`
mkdir $mytmp
cp -r  /lun3local/LOGS/Bla/*  $mytmp


But look again in TMP


root@node1 tmp]# ls
31032008??         keyring-AwcgvZ  keyring-vezDPF  PuDvgcpUNl
BNOoWqk5wf         keyring-b0v1x2  keyring-X5NUNQ  ssh-NEPZcy6279
gconfd-oracle      keyring-DsKYob  keyring-X5ta9B  TUNei151L7


31032008??

why like this?

i am getting something like this on cygwin...
you shouldtry
dos2unix mysricpt.sh
, or saving as unix (with emacs for example)
you may try changing it  to:
#!/bin/bash
lmydate=`date +'%d%m%Y'`
mytmp="/tmp/"$lmydate
mkdir $mytmp

and see if $mytmp has ??? at the end, then you have a file as dos (dos has #10+#13 (carrriage return + line feed) unix has only line feed so it is taking the #10 extra.

Look this when i do it step by step works but with scritp dosent want...


[root@node1 lun3local]# logdir=/lun3local/igor/$(date +%Y%m%d)
[root@node1 lun3local]# mkdir -p $logdir
[root@node1 lun3local]# cp -rp /lun3local/LOGS/Bla/* $logdir
[root@node1 lun3local]# cat pp_rman
#!/bin/bash
logdir=/lun3local/igor/$(date +%Y%m%d)
mkdir -p $logdir
cp -rp /lun3local/LOGS/Bla/* $logdir
[root@node1 lun3local]# ./pp_rman
: bad interpreter: No such file or directory
[root@node1 lun3local]#


Can you explane me please ?

Your tags indicated you are running this on a Linux system.  What OS are you trying to run it on?

RedHat 4 hrm why ?? when i got step by step works but not in scirpt

Type in

which bash

and  

head -1 pp_rman | od -c

[root@node1 lun3local]# which bash
/bin/bash
[root@node1 lun3local]# head -1 pp_rman | od -c
0000000   #   !   /   u   s   r   /   b   i   n   /   b   a   s   h  \r
0000020  \n
0000021
[root@node1 lun3local]#

here you are

you see the \r there? only the \n should be there
he actually seeks for /usr/bin/bash\r not for /usr/bin/bash
that is the problem, use dos2unix again!

as i said before dos uses \r\n and unix only \n
