Shell Programming and Scripting

Hi all,

i am new to this forum, unix and shell scripting.

I would really appreciate if you all can help me here..

I have files coming in the below format

Code:

'filename20513'13May06:03:45

filename are characters..

like 'ABDDUT20513'13May06:03:45

i need it to be renamed as 'ABDDUT20513'

i tried

Code:

mv \'*\'${date}*  \'*\'

but its not working..

Help will be very much appreciated...

Thanks & Regards,
khman

Moderator's Comments:

As noted in later posts, it is not clear from the text provided by the original poster whether or not the single quotes are literal characters in the mentioned filenames. The single quotes provided by the OP have been preserved when CODE and ICODE tags were added.

Please use code tags as required by forum rules!

Are you sure those single quotes are part of the file name? If not, and with a recent shell, try (untested)

Code:

echo mv $FN ${FN%${FN#*20513}}

with FN a shell variable holding the file name.

Code:

$ FN="'ABDDUT20513'13May06:03:45"

$ echo $FN ${FN%${FN##*\'}}
'ABDDUT20513'13May06:03:45 'ABDDUT20513'

You could also try:

Code:

FN="'ABDDUT20513'13May06:03:45"
echo mv "$FN" "${FN%\'*}'"

which produces the output:

Code:

mv 'ABDDUT20513'13May06:03:45 'ABDDUT20513'

So, if you remove the echo, it should rename the file the way you want it.

Thanks all for the reply & sorry for not using the code tags...
excuse me as I am just a beginner right now..

However, i feel it doesnt work..
i will explain in more detail...


i first find the files by the date, lets say 13May in a particular directory and uncompress them

Code:

 gunzip \'*\'${date}*

Then I change the permission

Code:

 chmod 777 \'*\'${date}*

After this Step, lets say I get a file as

Code:

 'ABDDUT20513'13May06:03:45

. This is value which i see in the runnnig the script in debug mode
This piece of code picks up the file

Code:

 \'*\'${date}*

file name can be anything but format will be the same as above.

now dynamically i need to rename whatever file comes

so for e.g. if it is

Code:

 'ABDDUT20513'13May06:03:45

Then output has to be

Code:

 'ABDDUT20513'

Another example: Lets say file name is 'ABCCDT20515'15May05:17:38.Z

Then expected output is

Code:

 'ABCCDT20515'

.

This renamed file has to be placed in the same directory then.

Kindly help.

I really appreciate your replies and kindly bear with me.
I am just in learning stages of Shell scripting

OK Let's get back to basics. You have been given suggestions that should work with any POSIX conforming shell.

What operating system are you using?

What shell are you using?

Hi Don,

Kindly brief about % in code echo mv "$FN" "${FN%\'*}'"
Thanks,
