for-loop for every folder in a directory, excluding some of them

Question

Thank you very much in advance for helping!

I have this code in bash:

for d in this_folder/*    
    do    
        plugin=$(basename $d)
        ech         


        

Answer 1

If you have a recent version of bash, you can use extended globs (shopt -s extglob):

shopt -s extglob

for d in this_folder/!(global|plugins|css)/   
do    
    plugin=$(basename "$d")
    echo $plugin'?'
    read $plugin
done

Answer 2

You could use find and awk to build the list of directories and then store the result in a variable. Something along the lines of this (untested):

dirs=$(find this_folder -maxdepth 1 -type d -printf "%f\n" | awk '!match($0,/^(global|plugins|css)$/)')
for d in $dirs; do
    # ...
done

Update 2019-05-16:

while read -r d; do
    # ...
done < <(gfind  -maxdepth 1 -type d -printf "%f\n" | awk '!match($0,/^(global|plugins|css)$/)')

Answer 3

You can use continue to skip one iteration of the loop:

for d in this_folder/*    
    do    
        plugin=$(basename $d)
        [[ $plugin =~ ^(global|plugins|css)$ ]] && continue
        echo $plugin'?'
        read $plugin
    done

While How to exclude some files from the loop in shell script was marked as a dupe of this Q/A and closed, that Q specifically asked about excluding files in a BASH script, which is exactly what I needed (in a script to check the validity of link fragments (the part after #) in local URLs. Here is my solution.

    for FILE in *
    do
        ## https://linuxize.com/post/how-to-check-if-string-contains-substring-in-bash/
        if [[ "$FILE" == *"cnp_"* ]]
        then
            echo 'cnp_* file found; skipping'
            continue
        fi
        ## rest of script
    done

Output:

    cnp_* file found; skipping

    ----------------------------------------
    FILE: 1 | NAME: linkchecker-test_file1.html
    PATH: /mnt/Vancouver/domains/buriedtruth.com/linkchecker-tests/linkchecker-test_file1.html

     RAW LINE: #bookmark1
    FULL PATH: /mnt/Vancouver/domains/buriedtruth.com/linkchecker-tests/linkchecker-test_file1.html#bookmark1

     FRAGMENT: bookmark1

    ...

My test directory contained 3 files, with one that I wanted to exclude (web scrape of an old website: an index with with tons of deprecated link fragments).

[victoria@victoria link_fragment_tester]$ tree
.

0 directories, 3 files

If you meant to exclude only the directories named global, css, plugins. This might not be an elegant solution but will do what you want.

for d in this_folder/*    
do  
    flag=1
    #scan through the path if it contains that string
    for i in "/css/" "/plugins/" "/global/"
    do

    if [[ $( echo "$d"|grep "$i" ) && $? -eq 0 ]]
    then
      flag=0;break;
    fi
    done

    #Only if the directory path does NOT contain those strings proceed
    if [[ $flag -eq 0 ]]
    then
    plugin=$(basename $d)
    echo $plugin'?'
    read $plugin
    fi


done
