Find, Grep and then Sed

nxvir · #1 (**permalink**) 10-17-2009

Example:
I have folders

456
abc
xyz
123
a1b

I dont want to find in 123 and a1b. From rest folder i need to find in html and php files.

find ./ -path "123" -prune and a1b

find ./ -iname "*.htm*" -o -iname "*.shtm*" -o -iname "*.php"

Now while finding i need to grep multiple words and then replace it one word.

example: grep (blue\|red\|yellow\|orange)

then put the result to text file.

After that i will pass a sed command and replace all the colorblack

My thought is something like this:

find ./ -path "123" -prune -o -path "a1b" -o -iname "*.htm*" -o -iname "*.shtm*" -o -iname "*.php" | xargs grep (blue\|red\|yellow) > temp.txt

for x in cat temp.txt do; sed -i 's/blue/black/g' $x; done

i have arround 10k files to replace, Can any one make it work?

Hi nxvir,

you can prune them like so, but then find will skip the content of those directories yet still list the directories themselves which will then still be passed as a parameter to xargs.

Code:

find ./ -path "*123" -prune -o -path "*a1b" -prune -o -iname "*.shtm" -o -iname "*.htm" -o -iname "*.php"

So I think it is better to not include the directories in find in the first place:

Code:

find ./!(a1b|123) -iname "*.shtm" -o -iname "*.htm" -o -iname "*.php"

For the grep statement:

Code:

egrep -l "blue|red|yellow"

should work.

Regarding the for statement:

Code:

for x in $(cat temp.txt) do

I think this might work without creating the tmp file: -

Code:

 
for x in $(find ./!(a1b|123) -iname "*.shtm" -o -iname "*.htm" -o -iname "*.php" | xargs egrep -l "blue|red|yellow" )
do
 
etc

i need to put the find result to text file is this right

Code:

 xargs egrep -l "blue|red|yellow" > temp.txt

then after that

for x in `cat temp.txt` do; 
sed -i 's/blue/black/g' $x; 
sed -i 's/yellow/black/g' $x; 
sed -i 's/red/black/g' $x; 
done

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

while run both given find command i get error

Code:

 find ./!(a1b|123) -iname "*.shtm" -o -iname "*.htm" -o -iname "*.php"
for x in $(find ./!(a1b|123) -iname "*.shtm" -o -iname "*.htm" -o -iname "*.php" 
| xargs egrep -l "blue|red|yellow" )

bash: !: event not found

wat may have caused this?

This command worked but as told by "Scrutinizer" it is true, still lists the directories which we ignored.

Code:

 find ./ -path "*123" -prune -o -path "*a1b" -prune -o -iname "*.shtm" -
o -iname "*.htm" -o -iname "*.php"

i tried by including -print

Code:

 find ./ -path "*123" -prune -o -path "*a1b" -prune -o -print 
-o -iname "*.shtm" -o -iname "*.htm" -o -iname "*.php"

this worked any taught?

I hate the history expansion, so I put this in my profile:
