I have 100 script files which has insert scripts for the table. How can I execute these? 

Scrip1.sql , script2.sql, script3.sql .... script100.sql

To execute single file, I am using the below command. But how can I execute all files? 

psql -d DBName -p 5444 -U schemaname -f P_Scrip1.sql  2> err.log

Create one file that calls all the others. – a_horse_with_no_name Oct 17 '16 at 12:38

If you don't need to provide a password, it's easy:

for FILE in `ls -1 *.sql`
do
  psql -d DBName -p 5444 -U schemaname -f $FILE  2>$FILE.err.log
done

If you need to provide a password, concatenate all of the files together, then run psql:

for FILE in `ls -1 *.sql`
do
  cat $FILE >> /tmp/allfiles.sql
done

psql -d DBName -p 5444 -U schemaname -f /tmp/allfiles.sql 2>allfiles.err.log

rm /tmp/allfiles.sql

@asalthangam: providing a password for that is a different question then "how do I run 100 SQL scripts" - see here for an answer to that: dba.stackexchange.com/questions/14740/… – a_horse_with_no_name Oct 17 '16 at 12:50

if you are using Linux you can use the following script

for ((i=1;i<101;i++)); do psql -d DBName -p 5444 -U schemaname -f P_Scrip${i}.sql 2> err.log & done

I wrote the script based on the information on the question, based on your comment, my solution will not work. Phil answer will do the trick. – Ahmad Abuhasna Oct 17 '16 at 12:59
