The sample you posted can't possibly be the contents of one single directory as there are duplicate filenames in it. If you want one task id listed regardless of the numerical suffix, try
Code:
sort -ut"-" -k1,1 file
sms_task_id_01-12345.csv
sms_task_id_02-12345.csv
sms_task_id_03-12345.csv

We are not getting desire output:
my position is now:
Quote:
pwd
/ap2/base/generate/

ls -lrth
sms_task_id_01-13345.csv
sms_task_id_01-14345.csv
sms_task_id_01-14345.csv
sms_task_id_02-12345.csv
sms_task_id_02-13345.csv
sms_task_id_02-14345.csv
sms_task_id_03-12345.csv
sms_task_id_03-13345.csv
sms_task_id_03-14345.csv
Now we want any single file according task_id like:
Quote:
sms_task_id_01-12345.csv
sms_task_id_02-12345.csv
sms_task_id_03-12345.csv

Well then try :
Code:
ls -rt | awk -F- '!A[$1]++'

Actually our file is like:
Code:
pwd
/ap2/base/generate/

ls -lrth
sms_task_id_01-13345.ab.csv
sms_task_id_01-14345.bc.csv
sms_task_id_01-14345.ce.csv
sms_task_id_02-12345.ae.csv
sms_task_id_02-13345.af.csv
sms_task_id_02-14345.ag.csv
sms_task_id_03-12345.ba.csv
sms_task_id_03-13345.al.csv
sms_task_id_03-14345.ai.csv

I want output:
Code:
sms_task_id_01-13345.ab.csv
sms_task_id_02-12345.ae.csv
sms_task_id_03-12345.ba.csv

Need one-one any file for task_id_01, task_id_02 & task_id_03

So you have a file that contains these strings:
Code:
pwd
/ap2/base/generate/

ls -lrth
sms_task_id_01-13345.ab.csv
sms_task_id_01-14345.bc.csv
sms_task_id_01-14345.ce.csv
sms_task_id_02-12345.ae.csv
sms_task_id_02-13345.af.csv
sms_task_id_02-14345.ag.csv
sms_task_id_03-12345.ba.csv
sms_task_id_03-13345.al.csv
sms_task_id_03-14345.ai.csv

And the file names start on the fifth line, is that what you are saying?

Have you tried any of the commands. What is your result?

Are you reading the posts? Applying them? Adapting them?
Code:
sort -ut"-" -k1,1 file
sms_task_id_01-13345.ab.csv
sms_task_id_02-12345.ae.csv
sms_task_id_03-12345.ba.csv
