Did you try this? It doesn't do what the poster wanted. It launches an interactive csh which gives the user a prompt, and interacts with the user until they exit the shell, at which time it goes on to the "ls -l". In other words, exactly the same as system( "csh" ); system( "ls -l" ). To run commands under the c shell, give them as an argument to csh: % perl -e 'system q(echo ~)' ~ % perl -e 'system q(csh -c "echo ~")' /home/peter >HTH, >Tanton >----- Original Message ----- >From: "Elanchezhian Sivanandam" <[EMAIL PROTECTED]> >To: "beginners" <[EMAIL PROTECTED]> >Sent: Thursday, October 31, 2002 1:45 AM >Subject: c shell commands in perl script > > >> hi, >> i have to give a set of commands from a perlscript in bash and c >> shell depending on an argument. >> since my default shell is bash the commands i give work. >> but for c shell the set of commands don't execute..... >> i mean the subsequent commands after i go to c shell (system >> "csh";) doesn't work. >> >> any suggestions??? >> thanks u -- Peter Scott http://www.perldebugged.com -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
