can you post sample input + output files? That will
make it easier.
stomp();
Here's some bash code, which should be a lot faster, because only shell builtins are used. Can be better if you bring samples(in/out) and explain them.
Code:
#!/bin/bash
shopt -s nocasematch
NUMBER=${TMFR//[wdhmoWDHMO]/}
# default multiplier for MINUTES
MULTIPLIER=60
# order of the checks matters!
[[ "$TMFR" =~ mo ]] && MULTIPLIER=2592000 # MONTH
[[ "$TMFR" =~ w ]] && MULTIPLIER=604800 # WEEK
[[ "$TMFR" =~ d ]] && MULTIPLIER=86400 # DAY
[[ "$TMFR" =~ h ]] && MULTIPLIER=3600 # HOUR
((FIRSTIN= $NUMBER * $MULTIPLIER))
echo $FIRSTIN $NUMBER $MULTIPLIER
thank you so much for this.
one question, this uses the newer functions of bash, i dont think it would work on the old bash that uses sh. know how to make this more portable?

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
