Hi, The following shows that diff -r print the command e.g. "diff -r /var/folders/ft/9trh7jt57kqc_hyq0wm5rny40000gx/T/tmp.wcrIdLELps/b.txt /var/folders/ft/9trh7jt57kqc_hyq0wm5rny40000gx/T/tmp.AJieJ9Zk1O/b.txt" if there is an error. I'm wondering if I just compare two files, it is possible to print the diff command if there is a difference between the two files? Thanks.
~/linux/test/gnu/diffutils/diff/-r$ cat main.sh #!/usr/bin/env bash dir1=$(mktemp -d) dir2=$(mktemp -d) echo 'Hello World' > "$dir1/a.txt" echo 'Hello World' > "$dir2/a.txt" echo 'Hello World' > "$dir1/b.txt" echo 'Hello World!' > "$dir2/b.txt" #echo 'Hello World' > "$dir1/c.txt" echo 'Hello World' | gzip -n > "$dir1/c.txt.gz" diff -r "$dir1" "$dir2" ~/linux/test/gnu/diffutils/diff/-r$ ./main.sh diff -r /var/folders/ft/9trh7jt57kqc_hyq0wm5rny40000gx/T/tmp.wcrIdLELps/b.txt /var/folders/ft/9trh7jt57kqc_hyq0wm5rny40000gx/T/tmp.AJieJ9Zk1O/b.txt 1c1 < Hello World --- > Hello World! Only in /var/folders/ft/9trh7jt57kqc_hyq0wm5rny40000gx/T/tmp.wcrIdLELps: c.txt.gz -- Regards, Peng
