Insert folder name in text string
Hi,

I am trying to organize a badly constructed web server. Basically every file is in public_html which is horrendous. There's about 50 images and 20 html files (not counting the css files and pdf docs).

I am trying to update each .html file using sed based on:
Where string contains *.jpg or *.gif or *.png
insert 'images/' before the filename.
i.e current HTML is
Code:
img src="image.jpg"

, I want to insert 'images/' in front of any jpg filename.

I tried
Code:
 sed 's/*.jpg /images/g' *.html

, but didn't work it just screen printed the file contents without updating anything.

Any help would be appreciated

Thanks

Enginama

Hello enginama,

Welcome to forums, thank you for using code tags as per forum rules Smilie.
Could you please try following and let me know if this helps you.
Code:
for file in *.html
do
    awk -vIMAGE="images\/" '/^img src/{gsub(/[^"]*.jpg|[^"]*.gif|[^"]*.png/,IMAGE"&",$0);} {print}' file > tmp_file
    mv tmp_file file
done

Also this will work in a specific directory, so if you want to run from a remote directory to all another directories then please change *.html to /my/complete/path/*.html.

EDIT: Also there is no need to put \ in vIMAGE="images\/" because while posting it here it is changing it to some other text so it avoid that I have done so in this post.

Thanks,
R. Singh

ok created sh script and placed it in directory with a single html file which had multiple occurences of gif and jpg's.

copied in the below code to the sh file as below:
Code:
for file in *.html
do
    awk -vIMAGE="images/" '/^img src/{gsub(/[^"]*.jpg|[^"]*.gif|[^"]*.png/,IMAGE"&",$0);} {print}' file > tmp_file
    mv tmp_file file
done

executed sh by
Code:
./changefiles.sh

On first attempt, it couldn't open 'file' for read but it did create an empty file called 'file'
Reran sh and it didn't produce an error, but no output either and 'file' still empty.
Checked permissions and user owns both html, sh (RWX)

Lost on what to do next.

Thanks for your help, it really is appreciated.

Hello enginama,

Could you please try following and let me know if this helps, it was having missing $file. Because I had not tested it.
Code:
for file in *.html
do
    awk -vIMAGE="images\/" '/^img src/{gsub(/[^"]*.jpg|[^"]*.gif|[^"]*.png/,IMAGE"&",$0);} {print}' $file > tmp_file
    mv tmp_file $file
done

Thanks,

Perhaps a this sed in a for loop written here :
Code:
sed 's#\(img src=\)"\(.*\.[jgp][pin][gf]\)"#\1"\2/"#g' "$file" > "$file.tmp" && mv "$file.tmp" "$file"

Above will not match case sensitivity, neither will awk solution, so PNG or Png will not be matched.
Regex would have to match capital letters [Pp] as well or use IGNORECASE if your awk supports it.

RavinderSingh13 your awk only match if a line is beginning with img=src or am i mistaken ?

Hope that helps

Peasant.

Sorry i cannot edit posts, a small correction :
Code:
sed 's#\(img src=\)"\(.*\.[jgp][pin][gf]\)"#\1"/my/new/path/\2"#g'

tried updated awk command. same effect, 'file' was still empty, no error messages either.
tried the sed line but getting BashSmilieermission denied error.
Below is a line of the code in one of the files I was referring to, hoping this helps a little:
Code:
<a href="https://www.facebook.com/pages/Charity/67484895"><img src="fb.jpg" alt="facebook" height="75" width="75"/></a>

Thankfully the original author was consistent with using lower case file extensions, so that won't be a concern.

Peasant's second, corrected sed command does what you expect
Code:
sed 'p; s#\(img src=\)"\(.*\.[jgp][pin][gf]\)"#\1"./images/\2"#g' file1
<a href="https://www.facebook.com/pages/Charity/67484895"><img src="fb.jpg" alt="facebook" height="75" width="75"/></a>
<a href="https://www.facebook.com/pages/Charity/67484895"><img src="./images/fb.jpg" alt="facebook" height="75" width="75"/></a>

You see the difference before/after; remove the p;in the beginning if happy; use redirection and mv to replace the original file.

RavinderSingh13's awk command needs another small correction to make it fly:
Code:
awk -vIMAGE="./images/" '1;/img src/{gsub(/[^"]*.jpg|[^"]*.gif|[^"]*.png/,IMAGE"&");} {print}' file1
<a href="https://www.facebook.com/pages/Charity/67484895"><img src="fb.jpg" alt="facebook" height="75" width="75"/></a>
<a href="https://www.facebook.com/pages/Charity/67484895"><img src="./images/fb.jpg" alt="facebook" height="75" width="75"/></a>

You see the difference before/after; remove the 1;in the beginning if happy; use redirection and mv to replace the original file.

This site doesn't allow me to use images/ so I entered ./images/ - edit the directory string to taste.
