need to fine the value A756(in place of A756 we can have any of the value from these...A756 or B234 or C987 ) if we found any of the value with in the file the file name should be changed to File_ValueFound.txt
ex: File_A756.txt
the place of value is same always..

Thanks in advance..

Try this:

Code:

fv="A756"
v=`fgrep "$fv" test.txt`
if [[ -n $v ]]; then mv test.txt test_${fv}.txt; fi;

The basic logic is bellow to find and rename files having a matching string. You can add multi sreach string as per your requirement.

@Spacebar..
we dont know which one will be in the file ..it is either A756 or B234 or C987

Try this if the position of the records is always going to be in the 5th line and the string is 4 characters,

mv file.txt File_`sed -n '5p' file.txt | awk '{print substr($0,(length($0)-3))}'`.txt

Hi Athix,
the record position can be any where(not the 5th line each time) ...but the string length is always 4 characters..but if string exist it will be from 17th position from start of the line (any of the line)..

Only these 3 strings A756 or B234 or C987 to check ??? If NO, then on what basis, we can get the values of string from the input file ..

Be clear while providing the input and dont let us assume. This would eaten up our time to provide answers ..
