UNIX for Dummies Questions & Answers

hello guys
i need a command that take the words from multiple files and put them in another file this way: one word needs to appear only once in the destination file with small letters no matter how it appears in source files , the words from destination file needs to be alphabetical ordered and to be only 1 word per line
Can someone help me with this please ? or some tips please

Code:

awk 'BEGIN{OFS="\n"} {$0=tolower($0);$1=$1;print}' inputfilelist | sort -u > outputfile

is not working.....this only copy the content of a file

Code:

# cat 1.txt
A file with
some words in it
# cat 2.txt
A different file with some
other words
#  awk 'BEGIN{OFS="\n"} {$0=tolower($0);$1=$1;print}' 1.txt 2.txt | sort -u
a
different
file
in
it
other
some
with
words

If you're getting different results then you need to show what they are, what the inputs are, and what command you're actually using. Just "is not working" is not a useful description...

your command also extracts numbers... and if there is something la 10Roger it wil extract 10Roger and not just Roger

Code:

cat file1 file2 ... |tr '[A-Z ]' '[a-z\n]' |sort -u

True, but then the OP didn't specify that it shouldn't...
