So now i have a need to insert ' at the beginning of text and at the end in over 2000 files. The text is always the same and is always found on the first line of the files (there are over 2000 files). The text is ../../wp-blog-header.php and the finished text should look like '../../wp-blog-header.php'. How would i make a bash script to accomplish this or is it possible? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You have to fill that part in. Do you know the names of the files? If so, list them in the first section. Do you have a set of "find" criteria that will produce the target files? If so, use that section. Do you have a simple shell "glob" (wild-card) expression that will yield the proper targets? If so, use that. You didn't give any information about which files to operate on, so obviously I could not make that part of the sample / example script definite.

Shouldn't *.php yield the results i need as far as find the 2000 files?

How would I know? You didn't say anything about the files on which you wish to operate. Is the target set all files whose name end in ".php"? If so, then yes. If not, then no.

"Files" could be anything. Clearly, I could not write the script to select a set of files the criteria for which remain in your mind. If there's any regularity to the names of the files on which you wish the script to operate, then no, you don't need to type them. But so far, only you know those criteria so only you can write the code that will yield that list.

Only if 1. All target files are in one and the same directory 2. You are in that directory 3. All target files have extension .php 4. No other files in that directory have extension .php So you have to say something about your directory structure to answer that one. -- Jos van Kan registered Linux user #152704 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

First of all you did run the script unmodified, while Randall clearly mentioned in his code sample alternatives, marked by "# ... or xyz" So it is EITHER
# List files, either explicitly one.php two.php foo.php bar.php
OR
# ... or by using command substitution based on "find": $( find baseDir name='*.php' )
OR
# ... or "ls": $( ls $baseDir/*.php )
You obviously don't want the first method ;) Now you need to adapt the placeholder baseDir / $baseDir to reflect your setup. Let's use the last example, ls: ls ~/Documents/*.odt would list all *.odt files in my Documents directory (if there are any). You see, I replaced $baseDir by the actual base directory (hint hint baseDir ;) ) so change the $baseDir to your real path, and delete the other alternatives, and try again.

Presumably using the "--in-place=.bak" option makes that unnecessary. One could either back up all the target files (I'd probably tar them up) or use the in-place-with-backup option, but presumably doing both would be overkill.

I could just be tired, or your request is ambiguous. I can't determine if you just need to enclose the top line in single quotes in 2K files, or _all_ lines in 2K files. I'm assuming here your files are in the same directory. In the first instance, sed -i "1s/\(^.*$\)/'\1'/" input.txt In the second, sed -i "s/\(^.*$\)/'\1'/" input.txt You just want to change the input.txt to a bash for loop which catches all the relevant files.

For 2000 files the limit of the `*' expansion could be reached. Therefore you may use `find' together with a shell loop and the `ed' ... e.g. find <target_dir>/ -name '*.php' | \ while read php; do ed $php &> /dev/null <<-EOF 1 ,s/.*/'&'/ . w q EOF # ^^^ this is a <TAB>! done if you want to use shell special signs literal like `$' in your text you may use `"EOF"' instead of `EOF'. Please note that if you're using a `-' before the `EOF' or before `"EOF"' you are able to indent the second `EOF'/`"EOF"' with a tabulator sign. If the `-' is missed the `EOF'/`"EOF"' has to be placed at the very first beginning of the line. An other editor is the sed, with its inplace option `-i': find <target_dir>/ -name '*.php' | \ while read php; do sed -ri "1,1 s/.*/'&'/" $php done it is a bit shorter ... but ed is in some cases more powerfull. Nevertheless both editors allow to use other boundary characters as the `/' ... sometimes I use `s@old@new@' or `s!old!new!'.
