Find / sed on lnx/AIX/sun
Hello @all

first of all in the best case this script has to work on every os (lnx/aix/sun).

It's very simple what it should do.

I have a standard path and I'll call it for this example /myhome/scripts
Within this path there are more files and folders and some of them are tagged with "orig_*" or "*_orig" at the beginning or at the end.

Code:
directory (e.g)
/myhome/scripts/orig_runscript.sh
/myhome/scripts/etc/orig_daemon_cfg.cfg
/myhome/scripts/etc/multi/multi_orig.cfg
/myhome/scripts/orig_perl64/files/files1.file




Code:



/myhome/scripts/runscript.sh
/myhome/scripts/etc/daemon_cfg.cfg
/myhome/scripts/etc/multi/multi.cfg
/myhome/scripts/perl64/files/files1.file


I want to find all of these files/folders and want to rename all of them but without the orig.

What i come around with.

Code:
MY_HOME="/myhome/scripts"
FIND_ORIG="$MY_HOME/find_orig.out"

echo "rename all orig_ files"
find ${MY_HOME}/orig_* >> ${FIND_ORIG} 2>/dev/null
for LINE in `cat ${FIND_ORIG}`; do
	OLD_NAME=${LINE}
	NEW_NAME=${LINE} | sed -e 's/orig_//'
	mv ${OLD_NAME} ${NEW_NAME} >> ${INSTALL_LOG}
        echo "moved $OLD_NAME to $NEW_NAME"
done
echo "done with renaming"

I tested it on lnx and aix and $NEW_NAME got no input. So he cant mv anything because of a missing destination file. Dont know why.

Another problem is the find command itself. * is not working on lnx etc pp.


Hope some one can help here =)

kind regards

echo and backquotes are missing here


Code:
NEW_NAME=`echo ${LINE} | sed -e 's/orig_//'`

Better. Back tics are old way to do it.
Code:
NEW_NAME=$(echo ${LINE} | sed -e 's/orig_//')

Thanks a lot both options are working very well.
Are the brackets replacing the backticks? Or do they have another meaning?

Now i am trying to get every single option to work because,
Code:
[..]sed -e 's/orig_//[...]

is just catiching /path/path/orig_*.file and not /path/path/file_orig.file
Can i use the "?" here for a single wildcard?

sed -e 's/?orig?// so he will catch every single string with an orig in there even some very large stuff that the find command will find :P

Code:
/path/path/file_orig/path/path/path/file.log
/path/path/file/path/path/path/file.log#

kind regards

Brackets are used for testing.
Se more here:
Special Characters

Back tics `code` is replaced by more flexible parentheses $(code)
