i have to list some file with certain exemption

suppose for example i have two files

file1.log.1

file1.log.1.123

i want ls -ltr command to list only 1st type of files

so i want like this

ls -ltr *.log.*---------it should grep 1st kind of files but this command greps all the files both of type 1 and 2.

plz help me to list only those file of 1st kind

try ls -ltr | grep ".log.[0-9]$"

how many kinds of type 1 files do you have. For only those 2 types tested

# ls -ltr *.log.[1-9]

thanks now i m able to get 1st kinf of files.........

but 1st kind of files are also like this

file1.log.123

file1.log.12


file1.log.10

ls -ltr *.log.[1-9]--------its grepping those file which have till 9,even i wnt to grep all the numbers like for example file1.log.12.

if you are sure you do not have any other characters beside numbers

ls -ltr *.log.? *.log.?? *.log.???

ls -ltr *.log.[0-9]*

ls -ltr *.log.[0-9]  *.log.[0-9] [0-9] *.log.[0-9] [0-9][0-9]
