Bash Scripting: I want to open a set of .php files, and add line before html tag
I have a set of .php files in a folder, I want to add text just before these lines:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" >
What i want is to insert just before these lines in the html file. So just want to prepend that file before each docType declaration. However the DOCTYPE declaration is never on line 1, as there is loads of php lines before.
I have开发者_运维技巧 this current script (where FE is the folder containing all the scripts i want to edit):
for file in ${fe}*; do
echo "$file"
done
Thanks,
for file in ${fe}*; do
sed -i -e '/<!DOC/i Text to insert' "$file"
done
#!/bin/bash
shopt -s nullglob
text2add="my text to add"
for file in *.php
do
if [ -f "$file" ];then
sed -i.bak "/<\!DOCTYPE/ i $text2add" $file
fi
done
Or just simply
text2add="my text to add"
sed -i.bak "/<\!DOCTYPE/ i $text2add" *.php
If you want to do it recursively
find . -iname "*.php" -exec sed -i.bak "/<\!DOCTYPE/ i $text" "{}" +;
echo "line" | cat - yourfile > /tmp/out && mv /tmp/out yourfile
Taken from here: http://www.cyberciti.biz/faq/bash-prepend-text-lines-to-file/
Here is my proposition. It assumes that your text to insert is in a file named mytextfile.
for file in ${fe}*; do
awk '/!DOCTYPE/{printf"%s\n",text;}{print}' text="`cat mytextfile`" $file \
> /tmp/out
mv /tmp/out $file
done
for file in ${fe}*; do
mv $file temp
echo "YOUR STRING" > $FILE
cat temp >> $FILE;
done
Try this in perl:
perl -i.bak -p -e 's/\<\!DOCTYPE/text to replace\<\!DOCTYPE/ig' *.php
This one-liner will modify all your php files, replacing <!DOCTYPE with whatever you want + <!DOCTYPE -- you want to put it back in (-: This will also backup all the modified files with an extension of .bak, so you'll see ".php.bak" files after you run this.
The i refers to case insensitive and g is global, i.e., replace all in the file. I assume only have one, and it has the same case, so you can safely leave out the "ig" at the end.
