Go to UCSC table browser and select hg19 gene models from either ensembl/Refseq/Gencode, which is either a GTF or BED file.

If gene is on + strand, col-2 is TSS and if gene is on -ve strand, col3 is TSS.

I strongly recommend against downloading files from non-official repositories. Always download from the official sources like UCSC, GENCODE, etc. You have no control over what the uploader might have done with the file. Not saying it was not proper, it is just not guaranteed.

Download the GTF from their official repository at NCBI, then filter for entries of the type "transcript" and take the start coordinate for plus-strand features and end coordinate for bottom strand features. That's it.

Is there any tool for doing this or just a bash script ?

It's really just some if/else awk command.

For refGene_hg19_TSS.bed file, the TSS site of "-" strnad should subtract 1, because the bed file not contain the last coordinate.
