I have a renamed js file which I have to call in each of my php pages. Now I want to replace that old name with the new one using shell. what iam using is this:
sed -i ’s/old/new/g’ * but this is giving the following error:
sed: -e expression #1, char 1: unknown command: How can I do this replacement?
sed -i.bak 's/old/new/g' *.php to do it recursively
find /path -type f -iname '*.php' -exec sed -i.bak 's/old/new/' "{}" +; 
sed -i '' -e '...', as described in answers to stackoverflow.com/questions/12696125/sed-edit-file-in-placeThere are probably less verbose solutions, but here we go:
for i in *; do sed -i 's/old/new/g' "$i"; done Mind you, it will only work on the current level of the file system, files in subdirectories will not be modified. Also, you might want to replace * with *.php, or make backups (pass an argument after -i, and it will make a backup with the given extension).
sed: couldn't edit includes: not a regular file for many folders.
this one is very simple, without for or loop, and takes care of any number or nested directories
grep -rl 'oldText' [folderName-optional] | xargs sed -i 's/oldText/newText/g'
No such file or directory with this one and recursive directories.You are using Unicode apostrophes (RIGHT SINGLE QUOTATION MARK - U2019) instead of ASCII (0x27) apostrophes around your sed command argument.
I know I'm really late but still:
find . -type f -name "*.php"|xargs sed -i 's/old/new/g' 
For completeness, providing the OSX compatible version of the above accepted answer (to answer comment from @jamescampbell)
for i in *.php; do sed -i .orig 's/old/new/g' "$i"; done This command creates .orig backup files.
Try this:
ls | grep "php" > files.txt for file in $(cat files.txt); do sed 's/catch/send/g' $file > TMPfile.php && mv TMPfile.php $file done
