Using 'trim' PHP function in bash
Today during writing some scripts I had a need of using PHP function 'trim' in bash script. This code gave me perfect results: #!/bin/sh trim() { echo $1; } echo ">>$(trim 'right side ')<<" echo ">>$(trim ' left side')<<" echo ">>$(trim ' both sides ')<<" Of course, second part (with echo) was written to test different cases whether it works correctly. Solution found here.
