is a local copy of /etc/password file from each server SRV
Setting LASTLOGIN or LASTFAILEDLOGIN causes that inner do loop to break out to the next server after reading just the first line from the password file. If I comment out those two lines the do loop will cycle for every line in the password file.
Greeting,
The following script completes after reading only one record from the input file that contains many records. I commented out the "ssh" and get what I expect, an echo of all the records in the input.txt file. Is ssh killing the file handle?

truncate
TRUNCATE(1) User Commands TRUNCATE(1)NAME
truncate - shrink or extend the size of a file to the specifed size
SYNOPSIS
truncate OPTION... FILE...
DESCRIPTION
Shrink or extend the size of each FILE to the specified size
A FILE argument that does not exist is created.
If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole)
reads as zero bytes.
Mandatory arguments to long options are mandatory for short options too.
-c, --no-create
do not create any files
-o, --io-blocks
Treat SIZE as number of IO blocks instead of bytes
-r, --reference=FILE
use this FILE's size
-s, --size=SIZE
use this SIZE
--help display this help and exit
--version
output version information and exit
SIZE is a number which may be followed by one of the following suffixes: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P,
E, Z, Y.
SIZE may also be prefixed by one of the following modifying characters: `+' extend by, `-' reduce by, `<' at most, `>' at least, `/' round
down to multiple of, `%' round up to multiple of.
Note that the -r and -s options are mutually exclusive.
