make use of the name of files

fredao · #1 (**permalink**) 12-13-2006

there are a number of files under the folder myfolder:

myfolder:

a_file_1 a_file_2 a_file_3 ...
b_file_1 b_file_2 b_file_3 ...
....

how can I write a script to do following:

if the name of the file starts with a, append the content of this file to file Final;
if the name of the file starts with b and the third field is greater than 2, append the content of this file to file Final for twice;
else, add a line " ================ ".

thanks!

I need to make different operation based on the names of the files under a directory. therefore, I need to write a script, and extract a substring of a name, and ... as shown in the example

here is the frame of my script:

find ./files/* |

while read file

do

if [ the name of the file start with "S" ]?
then
run ./a script ?
elif [ the name of the file start with a number ]?
then
run ./b script?
fi
done

##############
my problem is the place marked with "?"

here's something to start with - good luck:

Code:

#!/bin/ksh

find . -type f | while read path
do

   file=$(basename "${path}")
   if [[ "${file}" == @(S*) ]]; then
      echo "[$path] run ./a script ?"
   elif [[ "${file}" == @([0-9]*) ]]; then
      echo "[$path] run ./b script ?"
   fi
done

P.S. pls do use vB Codes when posting code samples.
