Hi

i want to move the file oo.i to oo.r(example), actually
i don't know the file name but ending with .i
so how i will move the file *.i to *.r

regards

ravi

[kish_1]

are you looking for script to move the file, here u find the script
for i in `ls`
do
echo "==== $i ===="
/usr/bin/mv $i oo.i
done

[U.SivaKumar_2]

Hi,
If there is a single file *.r this will work
#mv *.r oo.i

Hi,

A better way:

Hi,

#!/sbin/sh

old=I
new=M

for file in *.$old
do
mv $file `echo $file | sed -e 's/.$old$/.$new/g'
done

Hope this helps. Regards.

Hi,

I missed out a grave accent (`) after the sed:

#!/sbin/sh

old=I
new=M

for file in *.$old
do
mv $file `echo $file | sed -e 's/.$old$/.$new/g'`
done

With pattern matching (e.g. using sed), you do not need to worry about the number of dots (.) you have as part of your filename.

Hope this helps. Regards.

Hi steven


Again Thanks lot. All your scripts works fine
thanks. but I did this way.

old=I
new=M

for file in `ls *.$old`
do
mv $file `echo $file | cut -d\. -f1,2,3`.$new
done

hi
Try the basename command for this

for file in *.I
do
mv $file `basename $file .I`.M
done

[perez Ilan]

Hi Ravi,

try the pattern-matching operators.

old=I
new=M

for file in `ls *.$old`
do
newfile=${file%.$old}.$new
mv $file $newfile
done

[Tom Maloy]

ksh has a construct that you can use instead of basename.

To replace the ending ".I" with ".M", use:

mv $ORIGINAL_FILE ${ORIGINAL_FILE%.I}.M

You do need to use the curly brackets.
