ls file1 file2 >newfile 2>&1
This simply makes a text file with two lines: file1 \n file2 could not be found. What I don't understand is that when you run this command: ls file1 file2 >newfile, it prints "file2 could not be found" to... (1 Reply)

mbk_cata_lib
MBK_CATA_LIB(1) MBK ENVIRONMENT VARIABLES MBK_CATA_LIB(1)NAME
MBK_CATA_LIB - define the mbk catalog directory
SYNOPSYS
c-shell running
setenv MBK_CATA_LIB path1:path2:path3:...:...:pathn
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.
Web : http://asim.lip6.fr/recherche/alliance/
E-mail : alliance-users@asim.lip6.fr
DESCRIPTION
MBK_CATA_LIB sets the directories that are to be searched thru for reading. When instanciating a cell for example, the first cell that is
found with the given name is loaded in memory.
The seaching mecanism first look in MBK_WORK_LIB(1), and then, in path1 thru pathn, in the order defined by the user when typing the setenv
command. This directories are considered to be, from a mbk point of view, read only.
The pathi arguments must be actually accessible pathes on your host machine.
ERRORS
"mbk_fopen : can't open file 'unix_path/file.xx' thru directories : path1, ..., pathn"
This occurs when either the unix path is irrelevent, or when the file doesn't exist. This can also be a unix right problem if the
file is not accessible for reading, but this is seldom.
EXAMPLE
setenv MBK_CATA_LIB ~fred/crechan/uom:/labo/sclib
DIAGNOSTICS
Only the first path may be given with a '~', since the shell extents it only when seen first.
SEE ALSO mbk(3), genlib(1), MBK_WORK_LIB(1).
