Hi,
see man chmod
chmod 700 filename
chmod u+s filename

# chmod +s file
# chmod 4700 file

Hi,
Here, setuid bit is set for the user, so that anyone can get the privilege of that particular user and execute them.

To set it on the new machine,
execute
#chmod u+s

Please refer this link for more info;

Can you please suggest - IF i want to replace e.g. 'hello' in many files under directory '/home/tmp/'. How can it be done using UX command?

Thanks for your help!

In the file's content or in the file name?
Case insensitive?
Word anchored?
All occurances, or just the first? perl line?

Content, all, anchored, case insensitive:

# cd /home/tmp
# perl -pi -e's/\bhello\b/goodbye/gi' *

File names, unanchored, case sensitive, first occurance only:
# cd /home/tmp
# perl -MFile::Copy -e'for$f{<* >){($x=$f)=~s/hello/goodbye/;move$f,$x}'

Enjoy, Have FUN! H.Merijn

for FILE in *${FN1}*

mv $FILE $(echo $FILE | sed "s/${FN1}/${FN2}/")
done
exit 0

Hello,
I wish to replace actually -
'/opt/prog/' with '/dev/'
Please suggest what could be the command for replacement (having / in string) in many
files.

Thanks

[H.Merijn Brand (procura]

Again, inside the file, or in the file name?

/ is not mandatory as delimiter:

'/opt/prog/' with '/dev/'

Inline replace:
# perl -pi -e's{/opt/prog/}{/dev/}g' *

Enjoy, Have FUN! H.Merijn

[panchpan]

Sorry - the string to be replaced is inside the files.

[spex]

This will replace all occurrences of "/opt/prog/" with "/dev/" within all files in /home/tmp:

#!/usr/bin/sh
DIRNAME=/home/tmp/
for FILE in ${DIRNAME}
do
sed 's/\/opt\/prog\//\/dev\//' < ${DIRNAME}/${FILE} > ${DIRNAME}/${FILE}.tmp
mv ${DIRNAME}/${FILE}.tmp ${DIRNAME}/${FILE}
rm ${DIRNAME}/${FILE}.tmp
done
exit 0

Hi:

> I wish to replace actually - '/opt/prog/' with '/dev/'

Using Perl, either escape the foward slash (which creates a hard-to-read "leaning toothpick") or change the substitution's delimiter (which Perl allows):

# cd /path && perl -pi -e 's/\/opt\/prog\//\/dev\//gi' *
or:

# cd /path && perl -pi -e 's%/opt/prog/%/dev/%gi' *

Regards!
