Top Forums Shell Programming and Scripting Copy of array by index value fails Post 303012775 by LMHmedchem on Thursday 8th of February 2018 09:53:57 PM

In so far as I have tested this, it works and gives the same output as my script.

Just to illustrate the difference between a working solution and a well formed solution, my script took 16+ minutes to reformat a file,
Code:
time ./_reformat.sh  044_MF_L-anserine.sdf  044_MF_L-anserine_mod.sdf  CompoundName  Identifier InChI=  044_

real    16m49.969s
user    1m34.920s
sys     2m9.546s

The code posted by Chubler_XL processed the same file in just over 1 second.
Code:
time ./_reformat4.sh  044_MF_L-anserine.sdf  044_MF_L-anserine_mod.sdf  CompoundName  Identifier InChI=  044_

real    0m1.219s
user    0m0.920s
sys     0m0.045s

Thanks, this will save many hours of waiting for my code to finish.

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 filename 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. SEE ALSO
