Hi, I would like to know how could I remove accentes and the symbols: º and ª of a text file with sed. Whis this command doesn't works :-( sed "s/í/i/g" filename Many thanks and sorry for my english!

These characters are UTF-16?

Please use this command
sed -e "s/\º//g" -e "s/\ª//g" tt1.txt> tt2.txt

I have tested it with this input
tt1.txt input file contains
helªlo º helªlo2º
helªlo3º

output file tt2.txt comtains
hello hello2
hello3

Sorry doesn't work me In te text, the caracter ª if I do a vi it show me well, but when I do a sed from this text shows me a extrange caracter in substitusion to ª, it shows me a interrogation mark like inside of a sqare if I try to paste the line where the character is (ctrl+c, ctrl+v) but it shows: on - 8� Any help?

That's why we need to know your locale settings.

avid@defekas:~$ echo $LANG es_ES.UTF-8 Thanks

sed -e 's/^[ ]*Width:[ ]*//' -e 's/[ ]*$//'`

try this way ..you need to change according to your format in the file
