{{{janson_> i have many files, named like '6540141.jpg 6540157.jpg 6540165.jpg' and i will check the two last digits (41,57,65) and move them into the dir with the same name. What will be the best commands to use for this? janson_> i think the easiest is to use find and something more janson_> mv ofc :D janson_> but i will need to use regexp i suppose greycat> for file in *.jpg; do x=${file%.jpg}; n=${x: -2}; echo mv "$file" $n; done koala_man> !pe greybot> Parameter Expansion. Expressions like ${foo%.mp3} and so on -- see man bash, and then search for Parameter Expansion. See also, and

janson_> find . -type f -name "*.jpg*" , now i need to cut out "51" in the file named "xyz51.jpg", how can i use parameter expansion for this? greycat> janson_: my complete solution wasn't good enough for you? janson_> greycat: ow, missed it. thanks}}}
