[SOLVED] break word into individual alphabets

sysmicuser · 03-03-2012, 04:49 AM

Hi all,

I am looking "ideally" into a sed one line which would do magic such as follows..

input: Oneword
Output:'O','n','e','w','o','r','d','\0'

At end of each word split, it should have '\0' is there any quick and samrt way with sed or any other language?

An awk solution:

Code:

$ echo Oneword | awk 'BEGIN{FS=""}{for (i=1;i<=NF;i++) printf "\x27%s\x27,",$i}END{print "\x27\\0\x27"}'
'O','n','e','w','o','r','d','\0'

The Field Separator set to the empty string take charge of splitting the string into individual characters. "\x27" is the hex code of the single quote.

Just for something slightly different:

Code:

echo Oneword | awk -F "" '{q="\047";$1=$1; print q$0q",\\0"q}' OFS="','"

@colucix and @frail.

This is simply fascinating, I am truly mesmerized by the beauty of awk !

Can you please explain me login in your awk one liners? I am still learning so your help would be highly appreciated.

Thank you

I will contribute a sed solution.

Input file:

Code:

nowisthetime
forallgoodmen
tocometotheaid
oftheirparty

Code:

sed "s/./&\',\'/g;s/^/\'/;s/$/\\\0\'/" $InFile > $OutFile

Output file:

Code:

'n','o','w','i','s','t','h','e','t','i','m','e','\0'
'f','o','r','a','l','l','g','o','o','d','m','e','n','\0'
't','o','c','o','m','e','t','o','t','h','e','a','i','d','\0'
'o','f','t','h','e','i','r','p','a','r','t','y','\0'

Explanation:
Starting with this: nowisthetime
we execute this: s/./&\',\'/g
to produce this: n','o','w','i','s','t','h','e','t','i','m','e','

That's a good intermediate result but we need to "dress up" the
beginning and end of each line, so ...

Then we execute this: s/^/\'/
to prefix each line with a single quote mark
to produce this: 'n','o','w','i','s','t','h','e','t','i','m','e','

Finally, we execute this: s/$/\\\0\'
to suffix each line with \0'
to produce the desired result: 'n','o','w','i','s','t','h','e','t','i','m','e','\0'
