Hello !
Question du tréfond du système de fichier.
Puisqu'il est question de "root-kit", je farfouille dans mon système
avec une Knoppix, et, ho surprise, je trouve dans /usr/bin un fichier
qui date un peu (06-2001) et qui se nomme "["
Ciel ! Qu'est-ce ?
Est-ce un moyen de masquer un nom de fichier ?
Y a-t'il un moyen de connaître le vrai nom ?

Je joint la sortie de strings qui est d'ailleurs différente de ls.

Try `%s --help' for more information.
Usage: %s EXPRESSION
  or:  [ EXPRESSION ]
  or:  %s OPTION
Exit with the status determined by EXPRESSION.
  --help      display this help and exit
  --version   output version information and exit
EXPRESSION is true or false and sets exit status.  It is one of:
  ( EXPRESSION )               EXPRESSION is true
  ! EXPRESSION                 EXPRESSION is false
  EXPRESSION1 -a EXPRESSION2   both EXPRESSION1 and EXPRESSION2 are true
  EXPRESSION1 -o EXPRESSION2   either EXPRESSION1 or EXPRESSION2 is true
  [-n] STRING          the length of STRING is nonzero
  -z STRING            the length of STRING is zero
  STRING1 = STRING2    the strings are equal
  STRING1 != STRING2   the strings are not equal
  INTEGER1 -eq INTEGER2   INTEGER1 is equal to INTEGER2
  INTEGER1 -ge INTEGER2   INTEGER1 is greater than or equal to INTEGER2
  INTEGER1 -gt INTEGER2   INTEGER1 is greater than INTEGER2
  INTEGER1 -le INTEGER2   INTEGER1 is less than or equal to INTEGER2
  INTEGER1 -lt INTEGER2   INTEGER1 is less than INTEGER2
  INTEGER1 -ne INTEGER2   INTEGER1 is not equal to INTEGER2
  FILE1 -ef FILE2   FILE1 and FILE2 have the same device and inode numbers
  FILE1 -nt FILE2   FILE1 is newer (modification date) than FILE2
  FILE1 -ot FILE2   FILE1 is older than FILE2
  -b FILE     FILE exists and is block special
  -c FILE     FILE exists and is character special
  -d FILE     FILE exists and is a directory
  -e FILE     FILE exists
  -f FILE     FILE exists and is a regular file
  -g FILE     FILE exists and is set-group-ID
  -h FILE     FILE exists and is a symbolic link (same as -L)
  -G FILE     FILE exists and is owned by the effective group ID
  -k FILE     FILE exists and has its sticky bit set
  -L FILE     FILE exists and is a symbolic link (same as -h)
  -O FILE     FILE exists and is owned by the effective user ID
  -p FILE     FILE exists and is a named pipe
  -r FILE     FILE exists and is readable
  -s FILE     FILE exists and has a size greater than zero
  -S FILE     FILE exists and is a socket
  -t [FD]     file descriptor FD (stdout by default) is opened on a terminal
  -u FILE     FILE exists and its set-user-ID bit is set
  -w FILE     FILE exists and is writable
  -x FILE     FILE exists and is executable
Beware that parentheses need to be escaped (e.g., by backslashes) for shells.
INTEGER may also be -l STRING, which evaluates to the length of STRING.
