These could be understood by anyone capable of reading the execution script - they would see the way you determine the true password.
And there are ways to build upon something like this - to take that first digit and understand it as the offset. I sort of did that here with the first digit being 3 and then taking character 2, then character 5 (2+3), then character 8 (5+3). I just forced the math rather than adding a couple commands to have the cut know what positions to cut.
I'm calling a program with a command line arguement containing a password. while the process is running anyone on the system can ps -ef and see the password. Is there a way to prevent this from happening.

I've also tried
PROGRAM `cat passfile`

Hello,
I am trying to figure out away to hide a command from users when performing a ps check. I have a ksh that purges a table in a database. If I perform a >ps -eaf |grep ksh, I get the login id and password. I do not want other users seeing this. Is there a way to hide this. The login... (5 Replies)
Hello. A bit of a puzzle here:
I have a 3rd party executable, which requires the following parameters:
parm1 = program_name, parm2=userid/password, parm3=additional flags.
We tried passing password as a variable, but you can do grep, and see what the password actually is
I found a bit... (2 Replies)
Hello all ,
I looked up this site for solutions to hide login info from ps -ef | grep like using a seperate file and store the password in that especially for oracle sqlplus scripts.
I just got this thought , But dont know how to implement this in UNIX.

cut
cut(1) User Commands cut(1)NAME
cut - cut out selected fields of each line of a file
SYNOPSIS
cut -b list [-n] [file]...
cut -c list [file]...
cut -f list [-d delim] [-s] [file]...
DESCRIPTION
Use the cut utility to cut out columns from a table or fields from each line of a file; in data base parlance, it implements the projection
of a relation. The fields as specified by list can be fixed length, that is, character positions as on a punched card (-c option) or the
length can vary from line to line and be marked with a field delimiter character like TAB (-f option). cut can be used as a filter.
Either the -b, -c, or -f option must be specified.
Use grep(1) to make horizontal ``cuts'' (by context) through a file, or paste(1) to put files together column-wise (that is, horizontally).
To reorder columns in a table, use cut and paste.
OPTIONS
The following options are supported:
list A comma-separated or blank-character-separated list of integer field numbers (in increasing order), with optional - to indi-
cate ranges (for instance, 1,4,7; 1-3,8; -5,10 (short for 1-5,10); or 3- (short for third through last field)).
-b list The list following -b specifies byte positions (for instance, -b1-72 would pass the first 72 bytes of each line). When -b and
-n are used together, list is adjusted so that no multi-byte character is split.
-c list The list following -c specifies character positions (for instance, -c1-72 would pass the first 72 characters of each line).
-d delim The character following -d is the field delimiter (-f option only). Default is tab. Space or other characters with special
meaning to the shell must be quoted. delim can be a multi-byte character.
-f list The list following -f is a list of fields assumed to be separated in the file by a delimiter character (see -d ); for
instance, -f1,7 copies the first and seventh field only. Lines with no field delimiters will be passed through intact (useful
for table subheadings), unless -s is specified.
-n Do not split characters. When -b list and -n are used together, list is adjusted so that no multi-byte character is split.
-s Suppresses lines with no delimiter characters in case of -f option. Unless specified, lines with no delimiters will be passed
through untouched.
OPERANDS
The following operands are supported:
file A path name of an input file. If no file operands are specified, or if a file operand is -, the standard input will be used.
USAGE
See largefile(5) for the description of the behavior of cut when encountering files greater than or equal to 2 Gbyte (2^31 bytes).
EXAMPLES
Example 1 Mapping user IDs
A mapping of user IDs to names follows:
example% cut -d: -f1,5 /etc/passwd
Example 2 Setting current login name
To set name to current login name:
example$ name=`who am i | cut -f1 -d' '`
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of cut: LANG, LC_ALL, LC_CTYPE, LC_MES-
SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 All input files were output successfully.
>0 An error occurred.
