Talking Doing a "find and replace all" in all files in a directory


Lets say that I have a directory with say 10 files.

I would like to find the word "Austria" in all these files and replace it with "Germany".

Note that I do not have perl in my cygwin distribution and so perl based commands do not work.

What is the command that will help me achieve the desired goal.

Thank you

First----cygwin is not really a Linux distro---it simply allows you to do some "Linux things" within Windows.

I'm assuming that you are using the BASH shell within Cygwin, and that the standard tools--eg SED-- are available.

If you want to operate on all files in the current directory, then this should work:
sed -i 's/Austria/Germany/g' *
this edits the files "in place"---ie the old version is not saved. To save to new names, it's a bit more involved.

Thanks for the replies. But this does not solve the underlying problem that I am trying to address.

I have a file. Lets Call it File1.

Step 1
File1a = File generated by executing the following command : sed -i 's/obj/ /g' File1.txt

File1b = File generated by doing a "replace all" for the keyword 'obj' on File 1.

Note that in essence this step involves removing the string "obj" everywhere in File1 i.e. replacing "obj" with nothing.

Step 2
File 2a = Resultant file obtained by doing a "grep -a Title File1a.txt"

File 2b = Resultant file obtained by doing a "grep -a Title File1b.txt"

The strange observation is that File 2a ~= File2b (~= does not equal)

I can make this description meaningful by uploading the actual files on to this site. However there is no space for any attachments and so I was wondering if I could send it to one of the repliers by email so that they can take a look at it.

I want to understand the reason as to why File2a ~= File2b. I need the result as described in File2b but the drawback of that is that I have to manually open the file and do the replace all. Find a command that enabled to have the File2b format is the best solution.

I welcome any new comments/clarifications.


P.S:The find and replace was done using wordpad
Also I see that it is possible to upload files to this site but the file sizes allowed are too small for the files that I want to upload. I have a zip file (332 Kb) containing the following 5 files:
that I can send to any one interested by email.

sed -i 's/obj/ /g' File1.txt
should replace the string 'obj' with a single space.

1. is that what you wanted ie space != "nothing" eg
replace with nothing ie delete string; no replacement
sed -i 's/obj//g' File1.txt

2. exactly how did you do the 'replace all' cmd?
