replace string in all the files

Hi,

I want to replace a string "abc" with "xyz" in all the files, in current directory and all its subdirectories. How to do that ?
I do not want to open each and every file and replace the string.

Thanx in advance,
Vaibhav

Hi vaibhavmishra,

try this

ls -R | while read i
do
     sed -e 's/abc/xyz/g' $i
done

oops

ls -R <name of directory to which you want to apply changes>| while read i
do
     sed -e 's/abc/xyz/g' $i > $i.new
done

moreover.. this will store modified files in filename.new

you can execute a mv in similar loop to replace old files with new ones

ls -R | while read i
do
     sed -e 's/abc/xyz/g' $i > $i.new
     mv -f $i.new $i
done

Alternatives.

Use find to get the file list:

for File in $(find . -type f -print)
do
   ...
done

Use ed to edit the files in place. No separate output file created:

ed - $File <<- EOF
g/abc/s/abc/xyz/g
w
EOF

riding on glassd's suggestion of using find

for i in `find . -type f -print`
do
    sed -e 's/abc/xyz/g' $i > $i.new
    mv -f $i.new $i
done

I will add my usual comment about checking the status before renaming the file, otherwise you can end up nobbling loads of files

sed 's/abc/xyz/g' $i >$i.new && mv $i.new $i

you have to decide if you want to split and the ratio too
