loop through all folders & files - change file/foldernames & content of files

roberto32 · 06-14-2014, 06:48 AM

I need bash script that'll loop through directory and all its subdirectories and rename all files and folders as well as contents of files (xml, txt files so easily edited e.g by vim) containing certain patterns ( 3 patterns to be exact). Sumarry : rename all files/folders and contents of files matching certain pattern. and my the file/foldernames also includes freespace. I've 3 paterns wk10 v15, wk10_v15, wk10v15 and all I need is to change that v15 to v35 or some other number

actually my code looks like this

Code:

 #!/bin/bash
$path =/home/robert/Templates/result_arch/*

for i in { $path.xml $path.txt $path.log }
do
vim $i | %s/wk10 && v05/wk10 && v15/gC%s/wk10_v05/wk10_v15/g && %s/wk10v05/wk10v15/g
:wq
done

for i in $path
do
find $ -name '*-wk10 v05-*' -exec bash -c 'mv $0 ${0/wk10 v05/wk10 v15}' {} \;
find $ -name '*-wk10_v05-*' -exec bash -c 'mv $0 ${0/wk10_v05/wk10_v15}' {} \;
find $ -name '*-wk10v05-*' -exec bash -c 'mv $0 ${0/wk10v05/wk10v15}' {} \;


#mv"$i" "`echo $i | sed 's/wk10 v05/wk10 v15/'`
#mv"$i" "`echo $i | sed 's/wk10_v05/wk10_v15/'`
#mv"$i" "`echo $i | sed 's/wk10v05/wk10v15/'`
done

This is a job for find and sed: use find to walk the tree, use sed to substitute one pattern for another pattern (wk10 v15, wk10_v15 or wk10v15 with wk10 v35, wk10_v35 or wk10v35 or whatever else you may choose).

Before you start, make a back up copy of the entire tree:

Code:

cd <some_directory>
cp -pr <original_directory> .

About renaming all files and folders: use this little shell program to rename all files and directories ("folders") substituting a space with an underscore (this is for fixing Windows Weenie file names).

Code:

ONE=1				# For getting singular/plural right (see below).

do
     echo "$filename" | grep -q " "         #  Check whether filename
     if [ $? -eq $FOUND ]                   #+ contains space(s).
     then
       fname=$filename                      # Yes, this filename needs work.
       n=`echo $fname | sed -e "s/ /_/g"`   # Substitute underscore for blank.
       mv "$fname" "$n"                     # Do the actual renaming.
       let "number += 1"
     fi
done   

if [ "${number}" -eq "$ONE" ]                 # For correct grammar.
then
	echo "${number} file renamed."
else 
	echo "${number} files renamed."
fi 

exit 0

Save that as, say, blank-rename and make it executable:

Code:

chmod 755 blank-rename

Then get into the parent directory that you want to fix and execute it:

Code:

cd <directory>
blank-rename

Handy for when you're dealing with Windows file names (we don't use space characters in file names in Linux). Hang on to it, it'll come in handy over time.

find is pretty easy:

Code:

cd <parent directory>
find . -type f

sed is also pretty easy (and you can do the substitution in place with sed):

Code:

sed -i 's/v15/v35/g' ${file}

or, if you have other patterns that contain v15:

Code:

s -i 's/wk10\ v15/wk10\ v35/;s/wk10_v15/wk10_v35/g;s/wk10v15/wk10v35/g' ${file}

Read the man page for find and sed for more options.

If you intend to actually rename files and directories (other than changing the spaces to underscores), that's a little more complicated (you can see how it's done in blank-rename). Need to know a little more about what you intend.

Putting it together

Code:

cd <directory>
for file in $(find . -type f)
do
     s -i 's/wk10\ v15/wk10\ v35/;s/wk10_v15/wk10_v35/g;s/wk10v15/wk10v35/g' ${file}
done

Give that a shot and see what happens (don't forget to make a back up of your tree first!).

Hope this helps some.
