I need a one line command for the below requirement.
Search all the files from the root directory and print only those files names whose file name length is less than 25.
I suppose we can do it with find command so开发者_如何学JAVAmething like below:
find / -type f |xargs basename ....
I am not sure about furthur command.
My GNU find supports this, unsure whether it's a part of standard find.
find / -type f -regextype posix-extended -regex '.*/.{1,24}$'
Alternatively, use find | grep.
find / -type f | egrep '.*/.{1,24}$'
find / -type f|egrep "/[^/]{0,24}$"
Alternatively if you only want to display the filename without the path:
find / -type f| egrep -o "/[^/]{0,24}$" | cut -c 2-
Using Bash 4+
shopt -s globstar
shopt -s nullglob
for file in **/*
do
file=${file##*/}
if (( ${#file} < 25 ));then echo "$file"; fi
done
Ruby(1.9+)
ruby -e 'Dir["**/*"].each {|x| puts x if File.basename(x).size < 25}'
After referring quickly some manuals i got to find awk to be more suitable and easy to understand.please see the below solution which i had came up with.
find / -type f|awk -F'/' '{print $NF}'| awk 'length($0) < 25'
may be there are some syntax errors.please correct me if i am wrong.
