Search and Replace.

[teky]

Hi all,

I have about 150 html files in my unix system and my
company decided to change a word from x to y.
I need to replace the word in all the html files
in the sub directories too.
Replacing the word manually is a time consuming process.
Can anybody provide me with a script that replaces a word
from x to y in all the files.

Thanks,
Teky.

Hi,
Do the following:
go to the dir where all files are there.
open a file say test using vi editor.
give the following command (Esc :r! ls) --to list all files
then give (Esc :1,$s/^/vi )--to insert vi in front,note there's a space after vi
then give (Esc :1,$s/$/<change)--to append <change in end
save the file and quit.
open another file change using vi and type the following in insert mode1,$s/x/y) in first line and wq!) in second line.save this file and quit.
this is to replace x by y.
then execute the file test and yo all your files will replace the character x by y.


I hope u find this helpful......

Thanks Navin,

Why do we need the second file.
Anyway, I will try to execute this script.

Yes is a good one, you can also do all with a very simple shell script, on the example one to change &quot;teste&quot; to &quot;test&quot; on all files with extension html on directory &quot;/usr/local/myfiles&quot; and all subdirectories just do:

# sere.sh -ext html -dir /usr/local/myfiles teste test

Hope this helps,

#sere.sh
#! /bin/sh
usage() {
cat<<EOF
usage: $0 [-ext extension] [-dir directory_base] from_keyword to_keyword
EOF
exit 1
}

BASEDIR=&quot;.&quot;
EXT=&quot;&quot;

while : ; do
case $1 in
-dir) test $# -gt 1 || usage; BASEDIR=&quot;$2&quot; ; shift ;;
-ext) test $# -gt 1 || usage; EXT=&quot;$2&quot; ; shift ;;
-*) usage ;;
*)
break ;;
esac
shift
done

test $# -eq 2 || usage

if test -d &quot;$BASEDIR&quot; ; then : ; else
echo &quot;$BASEDIR: no such directory&quot;
exit 1
fi

case $EXT in &quot;&quot ;; .*) ;; *) EXT=&quot;.$EXT&quot; ;; esac
for file in `find &quot;$BASEDIR&quot; -type f -name &quot;*$EXT&quot; -print`; do
ed <<EOF $file >/dev/null 2>&1

EOF
done

If you have perl installed, you can use a really handy one-liner:

perl -pi -e 's/oldword/newword/gi' *.html

The switches at the command line (p,i,e) just say loop (p), edit the file in-place (i), and execute (e) the command (in single quotes, the gi = global, case-insensitive) on the filename = *.html.

If you want to make backup copies of the files before replacing them, use:

perl -p -e 's/old/new/gi' -i.bak *.html

It isn't recursive, but it should make it a bit easier.
