One thing really silly is the way digital cameras name their files : dsc00001.jpg<\/em> or something similar, which is quite annoying when you try to sort old pictures. So I made a small bash script that renames every picture with a more useful filename : 041131-001.jpg for example. To do so, I'm using a Perl script I've made, datemodif<\/a>, which outputs a modification date in various formats, but I wanted to do a more portable script, using only Bash and default GNU utils, but not Perl.<\/p>\n

After some testing, here is the function I've added to my .bash_profile :<\/p>\n

code<\/div>\n\n\t\t\n\t\t

  1. function getmodif {<\/div><\/li>\n
  2.    stat -c "%y" $1 | cut -d" " -f1 | sed -e 's\/..\/\/' -e 's\/-\/\/g'<\/div><\/li>\n
  3. }<\/div><\/li>\n<\/ol>\t<\/div>\n\n<\/div>\n\n

    Sample output :<\/p>\n
