Find

find . -type f | perl -ne 'print $1 if m/\.([^.\/]+)$/' | sort -u

  • Show all the file types on the directory.

find . -type f | awk -F. '!a[$NF]++{print $NF}'

  • -F fs --field-separator fs Use fs for the input field separator (the value of the FS predefined variable).
  • awk $NF prints only the last column in a record. If the file has only one row,
    your variable will contain whatever is in the last column (space/tab delimiter).

find . -type 'f' -printf '%h\n' | sort | uniq -c

  • The find command will print out the directory name of all the files. Which we then run through sort, and then use the -c option of uniq to give us the number of files per directory. Once you have the count per directory it should be easy enough to just grep out the directories with a value of 1.

  • If you would prefer to perform actions on the directories while keeping it on one line, you can pipe the results through awk to xargs. For example, to delete each folder: 

    find . -type 'f' -printf '%h\n' | sort | uniq -c | awk '{ if ($1 == "1") printf "%s%c",$2,0 }' | xargs -0 -I {} rm -rf {}

  • Avoid "Permission denied" messages 

    find ./ -iname "term" 2>&1 | grep -v "Permission denied"

Find info

  • Search in file a term and sort result 

    grep "texto a buscar" archivofuente.txt | grep -v -ie "comments" | sort -u > archivo.txt

  • Search in file URL and sort result uniques results 

    cat messages*.html | grep -Eo '(http|https)://[^<"]+' | sort -u

  • Search in file a term and know in what file is it 

    cat *.html | grep -H -R 'Goku'

  • Search unique URL term and order. 

    lynx -dump -listonly https://t.me/s/howtoarsenio | grep -o "http:.*" | grep -E -v "http://t.me|http://www.t.me" | sort | uniq > file.txt

List

  • Avoid a file type 
    ls -1 | sed -e 's/\.png$//'
