i have a small script automising the firefox invokation from my $HOME/bin
directory:
**********************
set FIREFOX_PATH='/tools/openbin/firefox/2.0.0.3/sparc-sun-solaris8'
set GTK_LIB_PATH='/tools/openbin/gtk+/1.2.10/sparc-sun-solaris8/lib'
set GLIB_LIB_PATH='/tools/openbin/glib/1.2.10/sparc-sun-solaris8/lib'
cd $FIREFOX_PATH
./firefox-bin &
cd
***********************
my question is
case:1
when i invoke the script sourcing it
source start_firefox.sh
it works
********************** case:2
when i do from $hOME/bin
tcsh start_firefox.sh
.......it works
******************* case:3
but when i do from $HOME/bin..here the script resides
./start_firefox.sh
error messages are coming like
*********
csbu061 [mhalder] 206: ./start_firefox.sh
./start_firefox.sh: setenv: not found
./start_firefox.sh: setenv: not found
./start_firefox.sh: setenv: not found
./start_firefox.sh: ./firefox-bin: not found
....i can understand its working while sourcing but i am confused why its working in the 2nd case while its not working in the 3 rd case
setenv is a tcsh built-in command, so you can only run it in a shell.
In cae 1, source tells your current (tcsh) shell to interpret and execute the commands in the file.
In case 2, you are creating a new tcsh shell which interprets and executes the commands in the file.
In case 3, it is not clear what is supposed to interpret the commands in the file, so it looks like a default sh shell is created to run them. setenv does not exist in sh,, hence the error message.
Putting
Code:
#!/bin/tcsh
at the top of your file will solve this and is effectively the same as case 2.

from the shell in $HOME/bin
