Hello all,
I have many files labeled: 001 _MP, 002 _MP...160 _MP
How do I rename all the files to 001_MP, 002_MP? That is remove the space?
I may need to script this as this occurs quite often
Thanks for your time

if you are using bash, no need to use external tools
for files in *MP
do
 mv "$files" "${files// /}"
done

OK Thanks here's what I end up using:
#!/bin/sh
find . -name "* *"|while read file
do
target=`echo "$file"|tr -s ' ' '_'`
mv "$file" "$target"
done

This one is for Korn Shell.
#!/bin/ksh
for file in *MP
do
print $file | while read part1 part2
do
mv "$file" "$part1$part2"
done
done
ghostdog's bash solution is also excellent. Both his solution and mine avoid the need to go outside the shell to accomplish the task which is always the best way to do things. Your solution uses the find, echo and the tr commands unnecessarily.
