How to fix “touch: out of range or illegal time specification” with touch t- function












-2















I have lost the creation date of 500 photos and clips when I transmitted them from my camera to my mac. Fortunately the creation dates are still in the files' name (like P_20180615_131048_vHDR_Auto_HP.jpg ; V_20180616_071110_vHDR_Auto_OC0.mp4)
So I read through some guidances from the internet to make the below scripts to help me batch changing the dates from the name. As I am a newbie of shell scripting, I don't know what I've done wrong.



for f in *; do
t=“${f:2:4}${f:6:2}${f:8:2}${f:11:2}${f:13:2}.${f:15:2}”
touch -t $t "$f"
done



I put the date in the format that touch needs(201806151310.48), but still get the same error "out of range or illegal time specification: [[CC]YY]MMDDhhmm[.SS] [[CC]YY]MMDDhhmm[.SS]"
I've been tried to put a date in the script directly
touch like -t 201806151610.48 $f and it worked. It seems that I cannot apply $t and $f both variables at the same time under touch function.
I would be very grateful if anyone can help me.

  • change it to echo touch -t $t "$f" so you can see what it produces.

  • More generally, generate the sequence of commands to a file using echo whatever > commandlist.sh, then you can check the file with vi commandlist.sh and execute it using sh < commandlist.sh

Thank you all of you. I solve the problem by just eliminate the " " in the second line. As I echo $t, it show "201806151310.48". How silly am i!!
I use bash shell in Mac os, I wonder why Lester can run it smoothly.
BTW, happy new yearXD

            Monofisismo

            Image
            Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

            -5 1 I'm starting to learn about php trying to achieve the goal of make my first custom form. From what I understand, it's possible to collect data from a form you can compose and customize to get information like title, subtitle, uploaded images and of course the main text of a supposed post and collect them in an html file that the form itself plus a php file can store in a folder on my server. what i would like to understand better is if i can compose the form making it be able to include the collected information between pieces of code i don't wanna write anytime in the fields of the form. i also need to understand how to make it be able to save the final html file with a different suffix like an increasing number at the end of the name to be sure no older file created this way is going to be lost...
