hi dear experts, I am just installing ns-allinone-2.32 package in kubuntu, following the installing instruction, which is decribed in http://nsnam.isi.edu/nsnam/index.php/Installing_ns2.31_on_Ubuntu7.04.
The installing process of the package is successful. But in the next step, the changing of my environment variance in bashrc file cannot be recognized by my system. Following is the content of the bashrc file: # This line was appended by KDE # Make sure our customised gtkrc file is loaded. export GTK2_RC_FILES=$HOME/.gtkrc-2.0 # LD_LIBRARY_PATH OTCL_LIB=/data/bzhang/work/ns-allinone-2.31/otcl-1.13 NS2_LIB=/data/bzhang/work/ns-allinone-2.31/lib X11_LIB=/usr/X11R6/lib USR_LOCAL_LIB=/usr/local/lib export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB # TCL_LIBRARY TCL_LIB=/data/bzhang/work/ns-allinone-2.31/tcl8.4.14/library USR_LIB=/usr/lib export TCL_LIBRARY=$TCL_LIB:$USR_LIB # PATH XGRAPH=/your/path/ns-allinone-2.31/bin:/data/bzhang/work/ns-allinone-2.31/tcl8.4.14/unix:/data/bzhang/work/ns-allinone-2.31/tk8.4.14/unix NS=/data/bzhang/work/ns-allinone-2.31/ns-2.31/ NAM=/data/bzhang/work/ns-allinone-2.31/nam-1.13/ PATH=$PATH:$XGRAPH:$NS:$NAM when I tried to source this file by "$ source ~/.bashrc", I got such error message from the shell: [EMAIL PROTECTED]:bzhang/work/ns-allinone-2.32] 109) source ~/.bashrc export: Command not found.
