I have several file that I need to rename. I want to rename to remove the extension on all file (file without extension). I'll prefer a "find and exec" command in Linux but I'm open to other solutions. Thanks
Have
file.txt
file1.txt
file2.txt
file3.
Want
file
file1
file2
file3
You can rename command:
rename 's/\.[a-z]*$//g' file*
If you want to find all files in directory and subdirectories then you can use find command:
find . -name 'file*' | xargs rename 's/\.[a-z]*$//g'
Depending on the files' possible names, you can adjust the regex in the rename command.
A bash solution would be:
for fname in *.txt; do
[[ ! -e ${fname} ]] && continue
new=${fname%.*}
mv "$fname" "$new"
done
The line [[ ! -e ${fname} ]] && continue to guard against the scenario when there's file with .txt as extension.

I am trying to rename the files and directories using a text file separated by space.
The text file looks like this:
dir1-1 dir1_1
dir2-1 dir223_1
My command is as follows:
xargs -r -a files.txt -L1 mv
This command can rename only folders from dir1-1 to dir1_1 and dir2-1to dir223_1so on but it doesn't rename the files in the subdirectories. The files in the corresponding directories also have these prefix of these directories.
Looking forward for the assistance.
Assuming you don't have special characters(space of tab...) in your file/dir names,
try
perl_script=$(
echo 'chop($_); $orig=$_;'
while read -r src tgt; do
echo 'if (s{(.*)/'"$src"'([^/]*)}{$1/'"$tgt"'\2}) { print "$orig $_\n";next;}'
done < files.txt)
find . -depth | perl -ne "$perl_script" | xargs -r -L1 echo mv
Remove echo once you see it does what you wanted.
I want to write a code is shell scripting which will rename all the files of extension .txt in a current directory to extension .c .Suppose my current directory contains some 100 .txt file. This number is not fixed.
for f in *.txt; do echo mv "$f" "${f%.txt}.c"; done
Remove "echo" when you're satisfied it's working. See the bash manual for the meaning of "%" here.
See man rename. You can rename multiple files providing regexp substitution.
rename 's/\.txt$/.c/' *.txt
If you don't have rename in you system, you can use find:
find . -name '*.txt' | while read FILE; do echo mv "$FILE" "$(echo "$FILE" | sed 's/\.txt$/.c/g')"; done
Remove echo when you verify it does what you want.
awk can do this trick too:
kent$ ls *.txt|awk '{o=$0;gsub(/txt$/,"c"); print "mv "o" "$0;}'|sh
I want to delete email "sudar.dudi#in.xyz.com" from all the files which lies in a particular directory. I used the below command after searching a lot.
The problem with this command is, it keeps on searching other than the desired directories and due to this command my other files got corrupted.
Please help me to correct this:
rrcg0/utioi
(in utioi direcotry are my files and the files are with specific names
like mpp.properties.JKH,mpp.properties.KJL,mpp.properties.KHF
likewise)
yes n|for file in $(find . -type f)
do
sed 's/sudar.dudi#in.xyz.com//g' $file > $file.tmp
mv $file.tmp $file
done
You do not need find when you know the directory.
When you want to check that an entry given by ls is a file, you can use a test:
mydir=rrcg0/utioi
for file in ${mydir}/*
do
if [ -f "${file}" ]; then
sed 's/sudar.dudi#in.xyz.com//g' $file > $file.tmp && mv $file.tmp $file
fi
done
When you only want properies files you can use
for file in ${mydir}/*properties*
I have used &&. This makes sure the mv command will only be done when the redirection succeeded.
I did not use the sed -i option, that option is not always supported.
EDIT: What about spaces in the filename?
When you might have spaces in the filename, the above script must be corrected:
sed 's/sudar.dudi#in.xyz.com//g' "$file" > "$file.tmp" && mv "$file.tmp" "$file"
Make it simpler, try using exec option of find and GNU sed option for inline editing
find <absolute dir path> -name "*" -type f -exec sed -i '/hello/d' {} \;
You can make changes to the existing files also, as then there is no need to move the file. Include -i in sed command.

mydir=rrcg0/utioi
for file in ${mydir}/*
do
if [ -f "${file}" ]; then
sed -i 's/sudar.dudi#in.xyz.com//g' $file
fi
done
I am using the following command to extract the files with 7zip
7za x -p$passwd $file -o$outdir
there are many files getting extracted, i want to rename these files after extraction how can i do it with help of writing a script in ksh
files=`ls ABC_0722*.zip | xargs -r`
outdir="/abc/def/prq/xyz"
for file in $files; do
passwd=`echo $file| awk '{print substr($0,11,2)}'``echo ABC``echo $file| awk '{print substr($0,5,2)}'`
7za x -p$passwd $file -o$outdir
done
After the extraction I need to rename the files to abcdef.
After decompress all files, use a for loop looking for all normal files that are not symbolink links, replace the basename of the path and replace it with abcde plus a counter:
for f in $outdir/*; do
[[ -f $f && ! -L $f ]] && { ((++i)); mv -- "$f" "${f%/*}/abcde$i"; };
done
I am working on something and need to solve the following. I am giving a analogous version of mine problem.
Say we have a music directory, in which there are 200 directories corresponding to different movies. In each movie directory there are some music files.
Now, say a file music.mp3 is in folder movie.mp3 . I want to make a shell script such that it renames the file to movie_music.mp3 and put it in some folder that I mention to it. Basically, all the files in the subdirectories are to be renamed and to be put in a new directory.
Any workaround for this?
This script receives two arguments: the source folder and the destination folder. It will move every file under any directory under the source directory to the new directory with the new filename:
#!/bin.sh
echo "Moving from $1 to $2"
for dir in "$1"/*; do
if [ -d "$dir" ]; then
for file in "$dir"/*; do
if [ -f "$file" ]; then
echo "${file} -> $2/`basename "$dir"`_`basename "${file}"`"
mv "${file}" "$2"/`basename "$dir"`_`basename "${file}"`
fi
done
fi
done
Here is a sample:
bash move.sh dir dir2
Moving from dir to dir2
dir/d1/f1 -> dir2/d1_f1
dir/d1/f2 -> dir2/d1_f2
dir/d2/f1 -> dir2/d2_f1
dir/d2/f2 -> dir2/d2_f2
Bash:
newdir=path/to/new_directory;
find . -type d |while read d; do
find "$d" -type f -maxdepth 1 |while read f; do
movie="$(basename "$d" |sed 's/\(\..*\)\?//')"
mv "$f" "$newdir/$movie_$(basename $f)";
done;
done
Assuming the following directory tree:
./movie1:
movie1.mp3
./movie2:
movie2.mp3
The following one-liner will create 'mv' commands you can use:
find ./ | grep "movie.*/" | awk '{print "mv "$1" "$1}' | sed 's/\(.*\)\//\1_/'
EDIT:
If your directory structure contains only the relevant directories, you can expand use the following grep instead:
grep "\/.*\/.*"
Notice it looks file anything with at least one directory and one file. If you have multiple inner directories, it won't be good enough.
