Folks,
Is there a simple way to replace one digit by two digit using sed.
Example,
mydigit1918_2006_8_8_lag1.csv should be
mydigit1918_2006_08_08_lag01.csv.
I tried this way, but doesn't work.
echo mydigit1989_2006_8_8_lag1.csv|sed 's/]/0]/'
Thank you, (5 Replies)

I want to write/print a number through a shell script up to its last significant digit (LSD) after the decimal point.
Say,
x=10.00056000000000000
I want to print x as x=10.00056.
Note that x can be any thing so I cannot know the position of the LSD always.
Thanks. (16 Replies)

nice
NICE(1) General Commands Manual NICE(1)NAME
nice, nohup - run a command at low priority (sh only)
SYNOPSIS
nice [ -number ] command [ arguments ]
nohup command [ arguments ]
DESCRIPTION
Nice executes command with low scheduling priority. If the number argument is present, the priority is incremented (higher numbers mean
lower priorities) by that amount up to a limit of 20. The default number is 10.
The super-user may run commands with priority higher than normal by using a negative priority, e.g. `--10'.
Nohup executes command immune to hangup and terminate signals from the controlling terminal. The priority is incremented by 5. Nohup
should be invoked from the shell with `&' in order to prevent it from responding to interrupts by or stealing the input from the next per-
son who logs in on the same terminal.
FILES
nohup.out standard output and standard error file under nohup
SEE ALSO csh(1), setpriority(2), renice(8)DIAGNOSTICS
Nice returns the exit status of the subject command.
BUGS
Nice and nohup are particular to sh(1). If you use csh(1), then commands executed with ``&'' are automatically immune to hangup signals
while in the background. There is a builtin command nohup which provides immunity from terminate, but it does not redirect output to
nohup.out.
Nice is built into csh(1) with a slightly different syntax than described here. The form ``nice +10'' nices to positive nice, and ``nice
-10'' can be used by the super-user to give a process more of the processor.
