Hi
I am writing a bash script on Solaris, that should take n arguments, either appended to the script or taken as output from the last command (similar to grep). What I don't want is that the script waits for user input. In other words:

Hi all,
if I have a dir with a mixture of files and directories in it and one of the directories *only* has read permission for the owner and I am not the owner - will I see it with an 'ls -la'.
I do not have access to a unix box at present to try this out.

MD5SUM(1) User Commands MD5SUM(1)NAME
md5sum - compute and check MD5 message digest
SYNOPSIS
md5sum [OPTION]... [FILE]...
DESCRIPTION
Print or check MD5 (128-bit) checksums.
With no FILE, or when FILE is -, read standard input.
-b, --binary
read in binary mode
-c, --check
read MD5 sums from the FILEs and check them
--tag create a BSD-style checksum
-t, --text
read in text mode (default)
The following five options are useful only when verifying checksums:
--ignore-missing
don't fail or report status for missing files
--quiet
don't print OK for each successfully verified file
--status
don't output anything, status code shows success
--strict
exit non-zero for improperly formatted checksum lines
-w, --warn
warn about improperly formatted checksum lines
--help display this help and exit
--version
output version information and exit
The sums are computed as described in RFC 1321. When checking, the input should be a former output of this program. The default mode is
to print a line with checksum, a space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant),
and name for each FILE.
BUGS
Do not use the MD5 algorithm for security related purposes. Instead, use an SHA-2 algorithm, implemented in the programs sha224sum(1),
sha256sum(1), sha384sum(1), sha512sum(1), or the BLAKE2 algorithm, implemented in b2sum(1)AUTHOR
