On a Linux system I have a binary (bin.exe) which needs to read an input file (input.cfg), where the names of other data files (data.txt) are specified. Usually both binary, input file and data files were in the same directory. Now and for organization reasons I need binary file to be in $SOMEPATH/bin and input and data files in $SOMEPATH/input.

I do not know how to do this. If I try

$SOMEPATH/bin/bin.exe $SOMEPATH/input/input.cfg

I get

error, "data.txt" not found

One solution would be to include absolute of relative path of “data.txt” in input.cfg, but the binary does not accept this.

I thought about somehow fooling the binary so that it thinks it is in $SOMEPATH/input, so that I just do

$SOMEPATH/bin/bin.exe input.cfg

and it works, but I do not know whether this is possible. any hints?

    (cd $SOMEPATH/input && $SOMEPATH/bin/bin.exe input.cfg)

    This is assuming that the program is relying on the current working directory to find the files. If the program is trying hard to find them in the same location as the executable, by consulting /proc/<pid>/exe for example, then you may be out of luck.
