Convert Extension from Uppercase to Lowercase
 
Hi
I have several fonts in ~/.fonts directory. Some of these fonts' extension are in uppercase and some are in lowercase, like:
Code:
font1.TTF  font2.Ttf  Font3.tTF
font4.ttf  FONT5.ttF...
and I want to convert all these extensions to lower case, like:
Code:
font1.ttf  font2.ttf  Font3.ttf
font4.ttf  FONT5.ttf...
That is, I don't want to convert the fonts' name, but only want to convert its extension from uppercase to lowercase.
Kindly guide me that how can I do it with single command?
Thanks

a little bash script or one liner, depending on how you write it up.

Code:

#!/usr/bin/env bash

while read f
do
        path=${f%/*}
        filen=$(basename $f)
        ext=${filen##*.}
        file=${filen%.*}
        echo "mv -v $f $path/$file.${ext,,}"
       
done <<<$( find  /usr/local/share/fonts/TTF -type f -iname "*.ttf" )
yes there are other ways to do this...

Code:
for i in ~/.fonts/*;do
  if [[ ${i} != ${i,,[${i##*.}]} ]]
  then
      echo mv -v \"${i}\" \"${i,,[${i##*.}]}\"
  fi
done
if you are happy that the mobes are fine, pipe it to sh

or drop the echo ( and drop the \s )

Code:
fonts=(font1.TTF font2.Ttf Font3.tTF font4.ttf FONT5.ttF)

for i in "${fonts[@]}"; do echo "${i,,}"; done
font1.ttf
font2.ttf
font3.ttf
font4.ttf
font5.ttf

for i in "${fonts[@]}"; do echo ""${i%.*}".ttf"; done
font1.ttf
font2.ttf
Font3.ttf
font4.ttf
FONT5.ttf

^ all these will probably work.
Question is, why do you (think you) need this?

Firerat 09-13-2019 03:05 PM
oh, wait you wanted a single command ;)

Code:
EXT2ext() {
for i in "${@}";do
  if [[ ${i} != ${i,,[${i##*.}]} ]]
  then
      mv -v "${i}" "${i,,[${i##*.}]}"
  fi
done
}
stick that in ~/.bash_extras
Code:
. ~/.bash_extras

EXT2ext ~/.fonts/*
and if you have . ~/.bash_extras in ~/.bashrc you will have it every bash session

note the leading . ( short for source )

Thanks everyone. Each of these was working, however, I used following:
Code:
#!/usr/bin/env bash

while read f
do
        path=${f%/*}
        filen=$(basename $f)
        ext=${filen##*.}
        file=${filen%.*}
        echo "mv -v $f $path/$file.${ext,,}"
       
done <<<$( find  /usr/local/share/fonts/TTF -type f -iname "*.ttf" )
Thanks again :-)

After this change, do I need to regenerate fonts cache?

Firerat 09-14-2019 07:32 AM
well the filenames will be different.
so probably

It could be automagic
