Today I had a task to change the modification date of file. In Linux it could be done using command: touch -m -d "date" filename But 'touch' command under Mac OS X has different parameters and after using the same command we will get error: touch: illegal option -- d usage: touch [-acfm] [-r file] [-t [[CC]YY]MMDDhhmm[.SS]] file

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.
