重命名 shell 脚本中的文件

Question

I have several files like:

NEW_YORK_CITY_124.txt

ATLANTA_23.txt

BOSTON_DOWNTOWN_67.txt

'Phoenix River_012.txt'

'MIAMI Ocean-Drive_987.txt'

I would like to rename all the files by removing the underscore, space or hyphen in the name (with caps for the first letter of each word) but keeping it for the number, like:

NewYorkCity_124.txt

Atlanta_23.txt

BostonDowntown_67.txt

PhoenixRiver_012.txt

MiamiOceanDrive_987.txt

Thank you very much for your help.

Answer 1

Using GNU sed:

for i in *; do
    ext=${i##*.}
    name=${i%.*}

    name=$(echo "$name" |
    sed -E '
    s/.*/\L&/
    s/(^|[^[:alnum:]]+)(.?)/\U\2/g
    s/[0-9]+$/_&/')

    echo mv "$i" "$name.$ext"
done

This method is a bit inefficient, because it starts a new sed process for each name. But it does the job. There are some rename programs that have similar syntax to a sed substitution, you could also try one of those, with a similar a expression.
