Normally the diffault shell can not be changed by user in
Solaris system. Because chsh command is not available in
Solaris environment. But one can change the default shell
in Linux environment by using following command.

chsh -s /bin/ksh
After issuing this command it will ask for passeord and if
password is given successfully then default shell will be
changed. Here you have to give the full path of shell.

user can change using chsh command

Answer / tony

The real answer may be, to ask whoever has access to ROOT, to set your default Shell to another one. He or she should not do that, at least before asking you : why ?
Additionally, he would still be reluctant of making any changes, because of the impact it can have.
In normal situations, the correct Shell is setup at user setup, and is never changed. Command to do that are USERADD and USERMOD (and other I'm sure).

A file has multiple records each having three 30-bit long fields(field1,field2,field3).There is also a lookup file,LOOK_UP.dat.Now, we need to consider only the last ten digits of field1 and lookup the file LOOK_UP.dat. If there a match then field2 and field3 should replaced with corresponding data from the lookup file. otherwise that particular record,for which there is no match, should be stored in a seperate file.
