I have no idea I have spent a lot of hours dealing with this problem. I need to write script. Script should loop recursively through subdirectories in current directory. It should check files count in each directory. If file count is greater than 10 it should write all names of these file in file named "BigList" otherwise it should write in file "ShortList". This should look like
---<directory name>
<filename>
<filename>
<filename>
<filename>
....
---<directory name>
<filename>
<filename>
<filename>
<filename>
....
My script only works if subdirecotries don't include subdirectories in turn.
I am confused about this. Because it doesn't work as I expect. It will take less than 5 minutes to write this on any programming language for my.
Please help to solve this problem , because I have no idea how to do this.
Here is my script
#!/bin/bash
parent_dir=""
if [ -d "$1" ]; then
path=$1;
else
path=$(pwd)
fi
parent_dir=$path
loop_folder_recurse() {
local files_list=""
local cnt=0
for i in "$1"/*;do
if [ -d "$i" ];then
echo "dir: $i"
parent_dir=$i
echo before recursion
loop_folder_recurse "$i"
echo after recursion
if [ $cnt -ge 10 ]; then
echo -e "---"$parent_dir >> BigList
echo -e $file_list >> BigList
else
echo -e "---"$parent_dir >> ShortList
echo -e $file_list >> ShortList
fi
elif [ -f "$i" ]; then
echo file $i
if [ $cur_fol != $main_pwd ]; then
file_list+=$i'\n'
cnt=$((cnt + 1))
fi
fi
done
}
echo "Base path: $path"
loop_folder_recurse $path
I believe that this does what you want:
find . -type d -exec env d={} bash -c 'out=Shortlist; [ $(ls "$d" | wc -l) -ge 10 ] && out=Biglist; { echo "--$d"; ls "$d"; echo; } >>"$out"' ';'
If we don't want either to count subdirectories to the cut-off or to list them in the output, then use this version:
find . -type d -exec env d={} bash -c 'out=Shortlist; [ $(ls -p "$d" | grep -v "/$" | wc -l) -ge 10 ] && out=Biglist; { echo "--$d"; ls -p "$d"; echo; } | grep -v "/$" >>"$out"' ';'

My script is as shown:
it searches for directories and provides info on that directory, however I am having trouble setting exceptions.
if [ -d "$1" ];
then
directories=$(find "$1" -type d | wc -l)
files=$(find "$1" -type f | wc -l)
sym=$(find "$1" -type l | wc -l)
printf "%s %'d\n" "Directories" $directories
printf "%s %'d\n" "Files" $files
printf "%s %'d\n" "Sym links" $sym
exit 0
else
echo "Must provide one argument"
exit 1
fi
How do I make it so that if I search for a file it tells me that a directory needs to be inputted? I'm stuck on it, I've tried test commands but I don't know what to do.
You're missing your shebang in the first line of your script:
#!/bin/bash
I get correct results from your script if I add it:
Directories 1,991
Files 13,363
Sym links 0
You may have to set the correct execution permissions also chmod +x scriptname.sh?
Entire script looks like this:
#!/bin/bash
if [ -z "$1" ];
then
echo "Please provide at least one argument!"
exit 1
elif [ -d "$1" ];
then
directories=$(find "$1" -type d | wc -l)
files=$(find "$1" -type f | wc -l)
sym=$(find "$1" -type l | wc -l)
printf "%s %'d\n" "Directories" $directories
printf "%s %'d\n" "Files" $files
printf "%s %'d\n" "Sym links" $sym
exit 0
else
echo "This is a file, not a directory"
exit 1
fi
I'm trying to perform certain operation on each file in a directory but there is a problem with order it's going through. It should do one file at the time. The long line (unzipping, grepping, zipping) works fine on a single file without a script, so there is a problem with a loop. Any ideas?
Script should grep through through each zipped file and look for word1 or word2. If at least one of them exist then:
unzip file
grep word1 and word2 and save it to file_done
remove unzipped file
zip file_done to /donefiles/ with original name
remove file_done from original directory
#!/bin/bash
for file in *.gz; do
counter=$(zgrep -c 'word1\|word2' $file)
if [[ $counter -gt 0 ]]; then
echo $counter
for file in *.gz; do
filenoext=${file::-3}
filedone=${filenoext}_done
echo $file
echo $filenoext
echo $filedone
gunzip $file | grep 'word1\|word2' $filenoext > $filedone | rm -f $filenoext | gzip -f -c $filedone > /donefiles/$file | rm -f $filedone
done
else
echo "nothing to do here"
fi
done
The code snipped you've provided has a few problems, e.g. unneeded nested for cycle and erroneous pipeline
(the whole line gunzip $file | grep 'word1\|word2' $filenoext > $filedone | rm -f $filenoext | gzip...).
Note also your code will work correctly only if *.gz files don't have spaces (or special characters) in names.
Also zgrep -c 'word1\|word2' will also match strings like line_starts_withword1_orword2_.
Here is the working version of the script:
#!/bin/bash
for file in *.gz; do
counter=$(zgrep -c -E 'word1|word2' $file) # now counter is the number of word1/word2 occurences in $file
if [[ $counter -gt 0 ]]; then
name=$(basename $file .gz)
zcat $file | grep -E 'word1|word2' > ${name}_done
gzip -f -c ${name}_done > /donefiles/$file
rm -f ${name}_done
else
echo 'nothing to do here'
fi
done
What we can improve here is:
since we unzipping the file anyway to check for word1|word2 presence, we may do this to temp file and avoid double-unzipping
we don't need to count how many word1 or word2 is inside the file, we may just check for their presence
${name}_done can be a temp file cleaned up automatically
we can use while cycle to handle file names with spaces
#!/bin/bash
tmp=`mktemp /tmp/gzip_demo.XXXXXX` # create temp file for us
trap "rm -f \"$tmp\"" EXIT INT TERM QUIT HUP # clean $tmp upon exit or termination
find . -maxdepth 1 -mindepth 1 -type f -name '*.gz' | while read f; do
# quotes around $f are now required in case of spaces in it
s=$(basename "$f") # short name w/o dir
gunzip -f -c "$f" | grep -P '\b(word1|word2)\b' > "$tmp"
[ -s "$tmp" ] && gzip -f -c "$tmp" > "/donefiles/$s" # create archive if anything is found
done
It looks like you have an inner loop inside the outer one :
#!/bin/bash
for file in *.gz; do
counter=$(zgrep -c 'word1\|word2' $file)
if [[ $counter -gt 0 ]]; then
echo $counter
for file in *.gz; do #<<< HERE
filenoext=${file::-3}
filedone=${filenoext}_done
echo $file
echo $filenoext
echo $filedone
gunzip $file | grep 'word1\|word2' $filenoext > $filedone | rm -f $filenoext | gzip -f -c $filedone > /donefiles/$file | rm -f $filedone
done
else
echo "nothing to do here"
fi
done
The inner loop goes through all the files in the directory if one of them contains file1 or file2. You probably want this :
#!/bin/bash
for file in *.gz; do
counter=$(zgrep -c 'word1\|word2' $file)
if [[ $counter -gt 0 ]]; then
echo $counter
filenoext=${file::-3}
filedone=${filenoext}_done
echo $file
echo $filenoext
echo $filedone
gunzip $file | grep 'word1\|word2' $filenoext > $filedone | rm -f $filenoext | gzip -f -c $filedone > /donefiles/$file | rm -f $filedone
else
echo "nothing to do here"
fi
done
I have searched many forums and websites to create an ALAC collection from my FLAC collection with the same directory structure with no success. Therefore I coded my own shell script and decided to share here so others can use or improve on it.
Problems I wanted to solve:
Full automation of conversion. I did not want to go and run scripts
in each and every directory.
Recursive file search
Moving all the structure from one location to another by converting flac to alac and copying the artwork. nothing else.
I did not want flac and alac files in the same directory.(which the below
script I believe can do that)
Here is how the script turned out. It works for me, I hope it does for you as well. I am using Linux Mint and bash shell.
2014-12-08 - Made some changes and now it is working fine. Before it was creating multiple copies.
Usage is: ./FLACtoALAC.sh /sourcedirectory /targetdirectory
Here are some explanations:
Source: /a/b/c/d/e/ <- e has flac
/g/f/k <- k has artwork
/l <- l has mp3
Target: /z/u/v/g/f
when the command is run : ./FLACtoALAC.sh /a/b/ /z/u/
I want the structure look like:
/z/u/v/g/f <- f was already there
/c/d/e/ <- e had flac, so created with the tree following source (/a/b)
/c/g/f/k <- k had artwork, so created with the tree following source (/a/b)
not created l <- l did not have any of the png,jpg or flac files.
I do not want to create any directory that does not contain png, jpg or flac,
unless it is a parent to one of such those directories.
Now the updated code:
#!/bin/bash
if [[ $1 ]]

if [[ ${1:0:1} = / || ${1:0:1} = ~ ]]

Try this out:
#!/bin/bash
src_dir="in"
dst_dir="out"
find ${src_dir} -type f -print0|while IFS= read -r -d '' src_file; do
dst_file=${src_file/$src_dir/$dst_dir}
echo "src_file=${src_file} dst_file=${dst_file}"
mkdir -pv `dirname $dst_file`
# use above variables and run convert command with it here
done
To test how it works:
mkdir in out
cd in
mkdir 1 2 3
find . -type d -exec touch {}/foo {}/bar {}/baz \;
cd ..
./run_my_script.sh
Now you only need to attach your convert function/script/command/whatever and improve it to read src_dir and dst_dir from the command line (I would recommend man bash - > getopts)
I have a find script that automatically opens a file if just one file is found. The way I currently handle it is doing a word count on the number of lines of the search results. Is there an easier way to do this?
if [ "$( cat "$temp" | wc -l | xargs echo )" == "1" ]; then
edit `cat "$temp"`
fi
EDITED - here is the context of the whole script.
term="$1"
temp=".aafind.txt"
find src sql common -iname "*$term*" | grep -v 'src/.*lib' >> "$temp"
if [ ! -s "$temp" ]; then
echo "ΓΈ - including lib..." 1>&2
find src sql common -iname "*$term*" >> "$temp"
fi
if [ "$( cat "$temp" | wc -l | xargs echo )" == "1" ]; then
# just open it in an editor
edit `cat "$temp"`
else
# format output
term_regex=`echo "$term" | sed "s%\*%[^/]*%g" | sed "s%\?%[^/]%g" `
cat "$temp" | sed -E 's%//+%/%' | grep --color -E -i "$term_regex|$"
fi
rm "$temp"
Unless I'm misunderstanding, the variable $temp contains one or more filenames, one per line, and if there is only one filename it should be edited?
[ $(wc -l <<< "$temp") = "1" ] && edit "$temp"
If $temp is a file containing filenames:
[ $(wc -l < "$temp") = "1" ] && edit "$(cat "$temp")"
Several of the results here will read through an entire file, whereas one can stop and have an answer after one line and one character:
if { IFS='' read -r result && ! read -n 1 _; } <file; then
echo "Exactly one line: $result"
else
echo "Either no valid content at all, or more than one line"
fi
For safely reading from find, if you have GNU find and bash as your shell, replace <file with < <(find ...) in the above. Even better, in that case, is to use NUL-delimited names, such that filenames with newlines (yes, they're legal) don't trip you up:
if { IFS='' read -r -d '' result && ! read -r -d '' -n 1 _; } \
< <(find ... -print0); then
printf 'Exactly one file: %q\n' "$result"
else
echo "Either no results, or more than one"
fi
Well, given that you are storing these results in the file $temp this is a little easier:
[ "$( wc -l < $temp )" -eq 1 ] && edit "$( cat $temp )"
Instead of 'cat $temp' you can do '< $temp', but it might take away some readability if you are not very familiar with redirection 8)
If you want to test whether the file is empty or not, test -s does that.
if [ -s "$temp" ]; then
edit `cat "$temp"`
fi
(A non-empty file by definition contains at least one line. You should find that wc -l agrees.)
If you genuinely want a line count of exactly one, then yes, it can be simplified substantially;
if [ $( wc -l <"$temp" ) = 1 ]; then
edit `cat "$temp"`
fi
You can use arrays:
x=($(find . -type f))
[ "${#x[*]}" -eq 1 ] && echo "just one || echo "many"
But you might have problems in case of filenames with whitespace, etc.
Still, something like this would be a native way
no this is the way, though you're making it over-complicated:
if [ "`wc -l $temp | cut -d' ' -f1`" = "1" ]; then
edit "$temp";
fi
what's complicating it is:
useless use of cat,
unuseful use of xargs
and I'm not sure if you really want the editcat $temp`` which is editing the file at the content of $temp
I have about 100 directories all in the same parent directory that adhere to the naming convention [sitename].com. I want to rename them all [sitename].subdomain.com.
Here's what I tried:
for FILE in `ls | sed 's/.com//' | xargs`;mv $FILE.com $FILE.subdomain.com;
But it fails miserably. Any ideas?
Use rename(1).
rename .com .subdomain.com *.com
And if you have a perl rename instead of the normal one, this works:
rename s/\\.com$/.subdomain.com/ *.com
Using bash:
for i in *
do
mv $i ${i%%.com}.subdomain.com
done
The ${i%%.com} construct returns the value of i without the '.com' suffix.
What about:
ls |
grep -Fv '.subdomain.com' |
while read FILE; do
f=`basename "$FILE" .com`
mv $f.com $f.subdomain.com
done
