hi all ,
i am trying to link a file with another file present in some other location in tcl shell. This is the way i am doing it
if {[file exists "/data/athena_dev/tanvi/tcl/tanvi.log"]} {
file link /data/athena_dev/tanvi/tcl/tanvi.log "/data/athena_dev/tanvi/tanvi.tcl"
}
I am getting the error that /data/athena_dev/tanvi/tcl/ta nvi.log -- this path already exists.
What is t=wrong i am doing here, please point me to that .
Thanks
Tanvi
Hi.
It looks like your arguments are in the wrong order:
#!/usr/bin/env tclsh
# @(#) s2 Demonstrate "file link".
puts stdout ""
set version [ info tclversion ]
set message " Hello, world from tclsh ($version)"
puts stdout $message
puts stdout ""
if { $argc == 0 } then {
puts stdout " No command line parameters provided."
set file "stdin"
} else {
set i 0
puts stdout " Command line arguments:"
foreach arg $argv {
set m1 " $i $arg"
incr i
set m2 ""
if { [ file exists $arg ] } then {
set m2 [ join [ list "(" [ file type $arg ] ")" ] ]
}
puts stdout "$m1 $m2"
set file $arg
}
}
puts ""
exec rm -f a b
exec touch a
exec ls -lgG a >@stdout
puts ""
puts " Results for link b a"
file link b a
exec ls -lgG a b >@stdout
puts ""
exec rm -f a b
exec touch a
puts " Results for link a b"
file link a b
exec ls -lgG a b >@stdout
exit 0
producing:
% ./s2
Hello, world from tclsh (8.4)
No command line parameters provided.
-rw-r--r-- 1 0 May 23 14:12 a
Results for link b a
-rw-r--r-- 1 0 May 23 14:12 a
lrwxrwxrwx 1 37 May 23 14:12 b -> .../a
Results for link a b
could not create new link "a": that path already exists
while executing
"file link a b"
(file "./s2" line 43)
Found by experimentation.
Best wishes ... cheers,drl
