Yeah, but that syntax is: $ yes | parallel -N0 -j1 echo touch '{= $_=seq()*5 =}'.txt vs $ loop --count-by 5 -- touch $COUNT.txt UNIX is about using the right tool for the right job, not the same tool for every job. Let us remember the koan: A Unix novice came to Master Foo and said: “I am confused. Is it not the Unix way that every program should concentrate on one thing and do it well?” Master Foo nodded. The novice continued: “Isn't it also the Unix way that the wheel should not be reinvented?” Master Foo nodded again. “Why, then, are there several tools with similar capabilities in text processing: sed, awk and Perl? With which one can I best practice the Unix way?” Master Foo asked the novice: “If you have a text file, what tool would you use to produce a copy with a few words in it replaced by strings of your choosing?” The novice frowned and said: “Perl's regexps would be excessive for so simple a task. I do not know awk, and I have been writing sed scripts in the last few weeks. As I have some experience with sed, at the moment I would prefer it. But if the job only needed to be done once rather than repeatedly, a text editor would suffice.” Master Foo nodded and replied: “When you are hungry, eat; when you are thirsty, drink; when you are tired, sleep.” Upon hearing this, the novice was enlightened.
