Shell Programming and Scripting

Hi Friends,

Following script will replace "prd123" to "tst123" for all the .csh file the directry.

for i in *.csh
echo '$i'
do
ex - ${i} <<EOF
%s/prd123/tst123/g
wq!
EOF
done

Like this can I make a script which will delete the last line of all .csh file
in the directry.

Thanks in advnce !!!!

yes you can - '$d'
P.S. Pls use vB Codes when quoting code like so: [code]my code goes here[/code]

I am not sure about ex but it basically has the same syntax as sed and I think this command line is quite as clear (since vgersh99 pointed out the $d). If You can use sed instead.

This will remove the last line of all *.csh files in You current working directory. The -i options means edit in place, which means to replace the original.
Use the command line

if You want to keep the original with a bak extension.

PS
Btw, is this a test or assignment or something?

I love solving problems with one line of code:

Code:

perl -nli -e 'print unless eof' *.csh

And no loops!

The "sed" solution will work also if the "-i" flag is supported.

But sed is shorter!

Thanks Friends for your help.

Thanks a lot gus2000,

Yours coding working finely!!

Lakris ,
I tried your code in command prompt. but it thorws some errors.
$ sed -i -e '$d' *.csh
sed: illegal option -- i
$

-i option of sed - in place editing is available only with GNU sed
