You can simplify a little bit the line:
grep -i "^[ABCDEFOIS]{6}$" /usr/share/dict/words | tr '[:lower:]' '[:upper:]' | tr 'OIS' '015' |awk '{print "#" $0}'

asimjalis · 2022-10-01T20:24:09Z

You can replace ABCDEF with A-F

gabrielsroka · 2022-10-01T20:28:52Z

@sicpier , I was just coming here to post something similar, but grep doesn't work on my Ubuntu distro. I'd need egrep or grep -P

robsheldon · 2022-10-01T20:36:06Z

Do you like backslashes? Then sed is the tool for you:

sed -n 's/^[a-fios]\{6\}$/#\U&/p' /usr/share/dict/words | tr 'OIS' '015'

-n ignores non-matching lines; /#\U appends the # and upper-cases matching lines.

edit: forgot & could be used in place of a capturing expression.

For those of you with 256color terminals, here's one that shows each color:

sed -n 's/^[a-fios]\{6\}$/\U&/p' /usr/share/dict/words \
  | tr 'OIS' '015' \
  | gawk --non-decimal-data \
         '{print "\033[48;2;" \
                 ("0x"substr($0,1,2))+0 ";" \
                 ("0x"substr($0,3,2))+0 ";" \
                 ("0x"substr($0,5,2))+0 "m" \
                 "       \033[0m " \
                 $0}'

I thought about leaving the text inside each color block, but I'd want to invert the color for the text FG, which would take us even further from a "one-liner". I'm already wishing I could loop over each color-component inside the pipe, but I'd need to keep the hex form for the output:

# Save HEX, using it to replace awk's $0 at the end: 
sed -n 's/^[a-fios]\{6\}$/\U&/p' /usr/share/dict/words \
  | tr 'OIS' '015' \
  | { while read HEX; do \
        echo $HEX | fold -w2 | xargs -n3 bash -c 'printf "\033[48;2;%03d;%03d;%03dm      \033[0m '"$HEX"'\n" 0x$0 0x$1 0x$2'; \
      done; }

# Loop over components instead of passing printf 3 args, now without invoking bash:
sed -n 's/^[a-fios]\{6\}$/\U&/p' /usr/share/dict/words \
  | tr 'OIS' '015' \
  | { while read HEX; do \
        printf '\033[48;2;'; \
        echo $HEX | fold -w2 | xargs -I {} printf '%03d' 0x{} | fold -w3 | tr '\n' ';'
        printf 'm      \033[0m %s\n' "$HEX"; \
      done; }

# Re-introduce that messy sub-shell for fancy FG colors:
sed -n 's/^[a-fios]\{6\}$/\U&/p' /usr/share/dict/words \
  | tr 'OIS' '015' \
  | { while read HEX; do \
        printf '\033[48;2;'; \
        echo $HEX | fold -w2 | xargs -I {} printf '%03d' 0x{} | fold -w3 | tr '\n' ';'
        printf 'm\033[38;2;'; \
        echo $HEX | fold -w2 | xargs -I {} bash -c 'DEC=$(printf "%d" 0x'{}'); printf "%03d" "$((255 - DEC))"' | fold -w3 | tr '\n' ';'
        printf 'm %s \033[0m %s\n' "$HEX"; \
      done; }

I bet someone who knows Perl well could do an all-in-one.

while read -r word; do
    if [[ $word =~ ^[abcdefoi]{6,6}$ ]]; then
        word=${word//o/0}

karakfa · 2022-10-02T00:48:29Z

here is an all awk version, slightly more readable than the sed version

awk '{$0=toupper($0)} /^[A-FOI]{6,6}$/{gsub("I",1); gsub("O",0); print "#" $0}' file

antler5 · 2022-10-02T01:15:52Z

Pretty gosh darn happy with this now c:

Not pure bash, I think that the coreutils's conciseness (tr, fold, xargs) is indispensable and grep is just so much faster (something does feel a little slow, donno if it's the sub-shells, or the arrays, haven't put my finger on it). I think it's concise, and clear... so long as one knows <<<, <(), IFS, and overlooks the entire BG_RGB pipeline (for which one ought to know a relatively obscure feature of printf, xargs, and (new to me) fold). Gotta love shell.

while read -r WORD; do
  while read -r HEX; do
    IFS=" "
    read -r -a BG_RGB <<< "$(fold -w2 <<< $HEX | xargs -I {} printf '%d ' 0x{})"
    read -r -a FG_RGB <<< "$(for component in ${BG_RGB[*]}; do printf '%d ' $((255 - $component)); done)"
    IFS=";"
    printf '\033[48;2;'"${BG_RGB[*]}"'m\033[38;2;'"${FG_RGB[*]}"'m '"$HEX"' \033[0m %s\n'
  done < <(tr 'IOS' '105' <<< ${WORD^^})
done < <(grep -Pi "^[A-FIOS]{6,6}$" /usr/share/dict/words)
# time for a in {1..10}; do ... ; done
# real  0m7.699s
# user  0m8.047s
# sys   0m1.301s

Edit:

something does feel a little slow

It was xargs, 'bout 50% faster without it (specifically not because of any other change I made to refactor it out, though most tweaks do push it over real 0m4s).

while read -r WORD; do
  while read -r HEX; do
    IFS=$'\n'
    BG_RGB=( $(fold -w2 <<< $HEX | while read -r COMP; do printf '%d\n' 0x$COMP; done) )
    FG_RGB=( $(for COMP in ${BG_RGB[*]}; do printf '%d\n' $((255 - $COMP)); done) )
    IFS=";"
    printf '\033[48;2;'"${BG_RGB[*]}"'m\033[38;2;'"${FG_RGB[*]}"'m '"$HEX"' \033[0m %s\n'
  done < <(tr 'IOS' '105' <<< ${WORD^^})
done < <(grep -Pi "^[A-FIOS]{6,6}$" /usr/share/dict/words)
# time for a in {1..10}; do ... ; done
# real  0m3.908s
# user  0m3.711s
# sys   0m0.716s

Edit: sed is slightly faster than grep or awk (for matching words, on my machine), and dropping the nested while loop into what is now sed's pipeline saves a ton of time. This is as fast as I think it gets, at least without using awk or sed for more than just what grep can do.

while read -r HEX; do
  IFS=$'\n'
  BG_RGB=( $(fold -w2 <<< $HEX | while read -r COMP; do printf '%d\n' 0x$COMP; done) )
  FG_RGB=( $(for COMP in ${BG_RGB[*]}; do printf '%d\n' $((255 - $COMP)); done) )
  IFS=";"
  printf '\033[48;2;'"${BG_RGB[*]}"'m\033[38;2;'"${FG_RGB[*]}"'m '"$HEX"' \033[0m %s\n'
done < <(sed -n 's/^[A-FIOSa-fios]\{6\}$/\U&/p' /usr/share/dict/words | tr 'IOS' '105') \
# time for a in {1..10}; do ... ; done
# real	0m2.318s
# user	0m2.227s
# sys	0m0.464s

Edit: I gotta go to bed :c
But just as a quick and dirty point of comparison, has an (extra) advantage bc the loop is unrolled (not that it makes a difference):

#!/usr/bin/env -S awk --non-decimal-data -f
{$0=toupper($0)}
/^[A-FIOS]{6,6}$/ {
  gsub("I",1);
  gsub("O",0);
  gsub("S",5);
  print "\033[48;2;" \
        000+("0x"substr($0,1,2)) ";" \
        000+("0x"substr($0,3,2)) ";" \
        000+("0x"substr($0,5,2)) "m" \
        "\033[38;2;" \
        255-("0x"substr($0,1,2)) ";" \
        255-("0x"substr($0,3,2)) ";" \
        255-("0x"substr($0,5,2)) "m" \
        " #" $0 \
        " \033[0m"; }
# time for a in {1..10}; do ... ; done
# real	0m0.539s
# user	0m0.532s
# sys	0m0.008s

Where is #BADA55 (or this is clean version)?

@dainiuxt it's on the "enable" list that my script uses

What if you take into account hex codes with 3 characters?
