UNIX for Dummies Questions & Answers

Hi All,

I need to rename the file names.

I need to rename for example as follows

file001 to flat1
file100 to flat100

Thanks

Will your filename always end with 3 digits ?

Vino

#! /bin/ksh
i=0
for list in `ls -l file*`
do
if [ $i -lt 99 ]
then
tmp=`echo $list| sed "s/^[a-z]*[0-9]*$/flat$i/"`
mv path_to_dir/$i path_to_dir/$tmp
i=$((i+1)) ;
fi
tmp=`echo $list| "sed s/^\([a-z]\)\([0-9]*\)/flat\2/"`
mv path_to_dir/$i path_to_dir/$tmp
done < /tmp/files.txt


( not tested )

hi,

you can try this,

as far i had tested it works,
plz let me know if there are any errors or anything to be clarified

-----------------------------------------------------
for i in `ls flat*`
do
echo $i > cls
val=`awk '{print substr($i,length($i)-2,3);}' cls`
mv $i file`expr $val + 0`
done
rm -f cls
exit 0
-----------------------------------------------------

Can also use the rename command.

rename "file00" "flat" *.*
rename "file" "flat" *.*

Is it not for i in `ls file*` ??

that was a confusion

to rename from file* to flat* or
flat* or file*

anyway that was a good catch

i should have been even more careful


thanks
