Help with wildcards 2

[biot023]

If I wanted to do the Unix equiavlent of the DOS commands
ren *.tif *.TIF
or
ren *.pqo *.pez

...how would I do it?
& is there any helpful info on wildcards & commands in Unix that anyone could share?
Needily (as always),

Hi,

In unix we don't have such thing. But, you can achieve the same using shell script. Creat a script with name ren which take two parameters like rename utility of dos and write the simple logic to rename the files.

if you want, reply to this forum, i will write it for you

Mahesh

Man, if you could, that would be fantastic!
I have no unix shell script experience, but I'm cool with C, so if you could put that together, I would be massively grateful!

Thanks a tonne,

I thought at first this was an easy one, but I seems there isn't an straightforward way to do this in linux.
So I asked someone here at work who knows a whole lot more of it than I do.
You have to write a script for it.
Here goes...



>pico ren

#!/bin/sh
FILES=`ls *.tif`
for FILE in $FILES
do
BN=`basename $FILE .tif`
mv $FILE $BN.TIF
done

>chmod 777 ren
>./ren

and this should work. I have a linux tutorial on pdf, if you give me your email adres, I'll send it to you.


Good luck.

Hi,

Here is a sample code for that. You can use it at command prompt like this ..
$ren .gif .bmp

remember that .. don't put *.gif or any extention with *. It's not that scalable

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
#!/bin/sh

if [ -z "$1" -a -z "$2" ]
then
echo "Incomplete arguments ..."
echo "Usage: $0 .old_ext .new_ext"
exit 1
fi

Replace="$1"
Replacewith="$2"

OldSuffix="."`echo $Replace | awk -F. '{print $2}'`
NewSuffix="."`echo $Replacewith | awk -F. '{print $2}'`

for file in *
do
CheckSuffix="."`echo $file | awk -F. '{print $2}'`
if [ "$CheckSuffix" == "$OldSuffix" ]
then
FileName=`basename $file $OldSuffix`
echo mv $file $FileName"$NewSuffix"
mv $file $FileName"$NewSuffix"
fi
done
>>>>>>>>>>>>>>>>>>>>>>>>>>>>

I named it ren.sh and then executed it as ren.sh .sh .rsh

and the name became ren.rsh

hope this is ok for you.

Hey, you can delete those two lines ...
here is the modified one ..

#!/bin/sh

if [ -z "$1" -a -z "$2" ]
then
echo "Incomplete arguments ..."
echo "Usage: $0 .old_ext .new_ext"
exit 1
fi

OldSuffix="$1"
NewSuffix="$2"

for file in *
do
CheckSuffix="."`echo $file | awk -F. '{print $2}'`
if [ "$CheckSuffix" == "$OldSuffix" ]
then
FileName=`basename $file $OldSuffix`
echo mv $file $FileName"$NewSuffix"
mv $file $FileName"$NewSuffix"
fi
done
