Hi Guys... can you tell me how to search between 2 variables ?... Im looking for a script that will move the data between varying words to separate files. I dont have my data on which I need to work right now... but it looks something like this..

start name1
data(a)
data(b)
stop name1
-------------------
start name2
data(c)
data(d)
stop name2
-----------------......... the list continues....what Im trying to do here is to extract the data between 'start name 1' and 'stop name1' and put it to a file and call it name1..Hope you guys can help me with this soon.....many thanks!!!

Try this following:

Code:
flag=0; 
while read line;
do  

    if [[ $flag -eq 1 ]]; 
    then    
        echo $line | grep -qv "stop" 
    	if [[ $? -eq 0 ]]; 
   	then         
   	     echo "$line" >> ${FILENAME}
   	fi;     
    fi; 
    echo $line | grep -q "start"; 
    if [[ $? -eq 0 ]]; 
    then     
        flag=1; 
        FILENAME=$(echo $line | awk '{ print $2; }')
        touch ${FILENAME}
    fi; 
    echo $line | grep -q "stop"; 
    if [[ $? -eq 0 ]]; 
    then     
        flag=0; 
    fi; 
    


done < file.log

May not be efficient but it works Smilie

With filelist for viewing and further use
bash code:
  1. #!/bin/bash
  2. i=0   #### You can remove if you don't want the file list
  3. while read -a L
  4. do
  5.    &#91; "${L[0]}" = start ] && { OUT=${L[1]}; FILES[$i]=$OUT; ((i++)); :>$OUT; continue; }   #### Remove FILES[$i]=$OUT; ((i++)); if you don't want filelist.
  6.    &#91; "${L[0]}" = stop ] && { OUT=""; continue; }
  7.    &#91; -n "$OUT" ] && echo "${L[*]}" >> $OUT
  8. done < infile
  9. ##### You can remove all the following if you don't want the file list
  10. for ((i=0; i<${#FILES[@]}; i++))
  11. do
  12.    echo "------------------"
  13.    echo "File: ${FILES[$i]}"
  14.    cat ${FILES[$i]}
  15. done
Without filelist
bash code:
  1. #!/bin/bash
  2. while read -a L
  3. do
  4.    &#91; "${L[0]}" = start ] && { OUT=${L[1]}; :>$OUT; continue; }
  5.    &#91; "${L[0]}" = stop ] && { OUT=""; continue; }
  6.    &#91; -n "$OUT" ] && echo "${L[*]}" >> $OUT
  7. done < infile
