Top Forums Shell Programming and Scripting While loop is not reading next line in the file when IF condition is used. Post 302600003 by agama on Sunday 19th of February 2012 10:39:08 PM

A while loop with redirection or piped input reads from stdin. Ssh by default also reads stdin and ends up reading the remainder of the data intended for the while.

Add -n to your ssh command to prevent it from reading from stdin.

NAME
passwd - compute password hashes SYNOPSIS
openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] {password} DESCRIPTION
The passwd command computes the hash of a password typed at run-time or the hash of each password in a list. The password list is taken from the named file for option -in file, from stdin for option -stdin, or from the command line, or from the terminal otherwise. The Unix standard algorithm crypt and the MD5-based BSD password algorithm 1 and its Apache variant apr1 are available. OPTIONS
-crypt Use the crypt algorithm (default). -1 Use the MD5 based BSD password algorithm 1. -apr1 Use the apr1 algorithm (Apache variant of the BSD algorithm). -salt string Use the specified salt. When reading a password from the terminal, this implies -noverify. -in file Read passwords from file. -stdin Read passwords from stdin. -noverify Don't verify when reading a password from the terminal. -quiet Don't output warnings when passwords given at the command line are truncated. -table In the output list, prepend the cleartext password and a TAB character to each password hash. EXAMPLES
openssl passwd -crypt -salt xx password prints xxj31ZMTZzkVA. openssl passwd -1 -salt xxxxxxxx password prints $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a.. openssl passwd -apr1 -salt xxxxxxxx password prints $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0. 0.9.7a 2002-10-03 PASSWD(1)
