Shell Programming and Scripting

Hi i have a problem i am going to serch for files and i have a bash script
but the problem i have is that the file names are like bser00001, bser00002 etc. and when i serch for files it start to serch for bser1, bser2, etc how can i do so it counts 00001, 00002 etc.

i wrote in a while loop and n is counting from 0 to 10000

bser$n


second problem is when it have find the file then make a folder with the file name. if i find a file name bser00001.txt then the folder name would be bser00001

Hi,
consider using the programs seq and basename.

for example, seq -w 00001 4 or seq -w 1 00004 will give You a sequnce of whole numbers that will be the width of the widest number.

and basename $filename .txt will give You the bser00001 part of the name.

On the other hand, if You know that all files start with bser followed by five digits, You already have the name after using seq, I guess.

Thanx for your answer but i am realy bad at scripting...
hmmm i dont realy understand i am a newbi can you give me a exampel code ? the name is always start with bser and i will count from 00001 to 10000
how do i implement it in my code it is like


#!/bin/sh
n=0

while [[ $n != 10000 ]] ; do

i have a code here....... bser$n ................and then i have a grep function

because of i dont have the code here so i cant attach it

Hi again,
You could do something like

Code:

#!/bin/bash
for x in $(seq -w 1 10000); do
grep "something" bser$x.txt
mkdir bser$x
echo finished with bser$x.txt
done

Could that be something to start with?

PS You can use a while too if You like, may be better for really big numbers...

Code:

#!/bin/bash
x=1
while [ $x -le 10000 ]  ; do
grep "something" bser$x.txt
mkdir bser$x
echo finished with bser$x.txt
x=$(($x+1))
done

i think that would work but

for x in $(seq -w 1 10000); do

you set the intreval from 1 to 10000 or is it mean that the highest nar is 10000 and you count up 1 at every time?

thanx a lot for you answers

I edited my last entry, so there's an example with while as well, if You refresh the page.

The for loop actually creates a list of numbers from 00001 (because of the -w parameter) to 10000, and the for loop executes once for each item in the list, setting x to that value. Thats why it may be better with the while variant because sometimes the list can be very large and in itself resource consuming.

look at it as

for x in 00001 00002 00003 00004 00005 ... and so on ... 09999 10000 ; do
something ...

Thanx very much i will try it tomorrow i hope it will work it will work with files with the name bser and have a interval from o to 100000000000000 if i change 10000 in the for loop or i mean in while loop.
